With news like this one cited by Bruce Schneier [1] people are asking whether it s worth using Secure Boot. Regarding the specific news article, this is always a risk with distributed public key encryption systems. Lose control of one private key and attackers can do bad things. That doesn t make it bad it just makes it less valuable. If you want to setup a system for a government agency, bank, or other high value target then it s quite reasonable to expect an adversary to purchase systems of the same make and model to verify that their attacks will work. If you want to make your home PC a little harder to attack then you can expect that the likely adversaries won t bother with such things. You don t need security to be perfect, making a particular attack slightly more difficult than other potential attacks gives a large part of the benefit. The purpose of Secure Boot is to verify the boot loader with a public key signature and then have the boot loader verify the kernel. Microsoft signs the shim that is used by each Linux distribution to load GRUB (or another boot loader). So when I configure a Debian system with Secure Boot enabled that doesn t stop anyone from booting Ubuntu. From the signatures on the boot loader etc there is no difference from my Debian installation and a rescue image from Debian, Ubuntu, or another distribution booted by a hostile party to do things against my interests. The difference between the legitimate OS image and malware is a matter of who boots it and the reason for booting it. It is possible to deconfigure Microsoft keys from UEFI to only boot from your own key, this document describes what is necessary to do that [2]. Basically if you boot without using any option ROMs (which among other things means the ROM from your video card) then you can disable the MS keys. If it s impossible to disable the MS keys that doesn t make it impossible to gain a benefit from the Secure Boot process. You can use a block device decryption process that involves a signature of the kernel and the BIOS being used as part of the decryption for the device. So if a system is booted with the wrong kernel and the user doesn t recognise it then they will find that they can t unlock the device with the password. I think it s possible on some systems to run the Secure Boot functionality in a non-enforcing mode such that it will use a bootloader without a valid signature but still use the hash for TPM calculations, that appears impossible on my Thinkpad Yoga Gen3 which only has enabled and disabled as options but should work on Dell laptops which have an option to run Secure Boot in permissive mode. I believe that the way of the future is to use something like EFIStub [3] to create unified kernel images with a signed kernel, initrd, and command-line parameters in a single bundle which can be loaded directly by the UEFI BIOS. From the perspective of a distribution developer it s good to have many people using the current standard functionality of shim and GRUB for EFI as a step towards that goal. CloudFlare has a good blog post about Linux kernel hardening [4]. In that post they cover the benefits of a full secure boot setup (which is difficult at the current time) and the way that secure boot enables the lockdown module for kernel integrity. When Secure Boot is detected by the kernel it automatically enables lockdown=integrity functionality (see this blog post for an explanation of lockdown [5]). It is possible to enable this by putting lockdown=integrity on the kernel command line or lockdown=confidentiality if you want even more protection, but it happens by default with Secure Boot. Secure Boot is something you can set to get a selection of security features enabled and get a known minimum level of integrity even if the signatures aren t used for anything useful, restricting a system to only boot kernels from MS, Debian, Ubuntu, Red Hat, etc is not useful. For most users I think that Secure Boot is a small increase in security but testing it on a large number of systems allows increasing the overall security of operating systems which benefits the world. Also I think that having features like EFIStub usable for a large portion of the users (possibly the majority of users) is something that can be expected to happen in the lifetime of hardware being purchased now. So ensuring that Secure Boot works with GRUB now will facilitate using EFIStub etc in future years. The Secure Boot page on the Debian wiki is worth reading, and also worth updating for people who want to contribute [6].

Short version: Secure Boot Advanced Targeting and if that's enough for you you can skip the rest you're welcome.

Long version: When UEFI Secure Boot was specified, everyone involved was, well, a touch naive. The basic security model of Secure Boot is that all the code that ends up running in a kernel-level privileged environment should be validated before execution - the firmware verifies the bootloader, the bootloader verifies the kernel, the kernel verifies any additional runtime loaded kernel code, and now we have a trusted environment to impose any other security policy we want. Obviously people might screw up, but the spec included a way to revoke any signed components that turned out not to be trustworthy: simply add the hash of the untrustworthy code to a variable, and then refuse to load anything with that hash even if it's signed with a trusted key.

Unfortunately, as it turns out, scale. Every Linux distribution that works in the Secure Boot ecosystem generates their own bootloader binaries, and each of them has a different hash. If there's a vulnerability identified in the source code for said bootloader, there's a large number of different binaries that need to be revoked. And, well, the storage available to store the variable containing all these hashes is limited. There's simply not enough space to add a new set of hashes every time it turns out that grub (a bootloader initially written for a simpler time when there was no boot security and which has several separate image parsers and also a font parser and look you know where this is going) has another mechanism for a hostile actor to cause it to execute arbitrary code, so another solution was needed.

And that solution is SBAT. The general concept behind SBAT is pretty straightforward. Every important component in the boot chain declares a security generation that's incorporated into the signed binary. When a vulnerability is identified and fixed, that generation is incremented. An update can then be pushed that defines a minimum generation - boot components will look at the next item in the chain, compare its name and generation number to the ones stored in a firmware variable, and decide whether or not to execute it based on that. Instead of having to revoke a large number of individual hashes, it becomes possible to push one update that simply says "Any version of grub with a security generation below this number is considered untrustworthy".

So why is this suddenly relevant? SBAT was developed collaboratively between the Linux community and Microsoft, and Microsoft chose to push a Windows update that told systems not to trust versions of grub with a security generation below a certain level. This was because those versions of grub had genuine security vulnerabilities that would allow an attacker to compromise the Windows secure boot chain, and we've seen real world examples of malware wanting to do that (Black Lotus did so using a vulnerability in the Windows bootloader, but a vulnerability in grub would be just as viable for this). Viewed purely from a security perspective, this was a legitimate thing to want to do.

(An aside: the "Something has gone seriously wrong" message that's associated with people having a bad time as a result of this update? That's a message from shim, not any Microsoft code. Shim pays attention to SBAT updates in order to avoid violating the security assumptions made by other bootloaders on the system, so even though it was Microsoft that pushed the SBAT update, it's the Linux bootloader that refuses to run old versions of grub as a result. This is absolutely working as intended)

The problem we've ended up in is that several Linux distributions had not shipped versions of grub with a newer security generation, and so those versions of grub are assumed to be insecure (it's worth noting that grub is signed by individual distributions, not Microsoft, so there's no externally introduced lag here). Microsoft's stated intention was that Windows Update would only apply the SBAT update to systems that were Windows-only, and any dual-boot setups would instead be left vulnerable to attack until the installed distro updated its grub and shipped an SBAT update itself. Unfortunately, as is now obvious, that didn't work as intended and at least some dual-boot setups applied the update and that distribution's Shim refused to boot that distribution's grub.

What's the summary? Microsoft (understandably) didn't want it to be possible to attack Windows by using a vulnerable version of grub that could be tricked into executing arbitrary code and then introduce a bootkit into the Windows kernel during boot. Microsoft did this by pushing a Windows Update that updated the SBAT variable to indicate that known-vulnerable versions of grub shouldn't be allowed to boot on those systems. The distribution-provided Shim first-stage bootloader read this variable, read the SBAT section from the installed copy of grub, realised these conflicted, and refused to boot grub with the "Something has gone seriously wrong" message. This update was not supposed to apply to dual-boot systems, but did anyway. Basically:

1) Microsoft applied an update to systems where that update shouldn't have been applied
2) Some Linux distros failed to update their grub code and SBAT security generation when exploitable security vulnerabilities were identified in grub

The outcome is that some people can't boot their systems. I think there's plenty of blame here. Microsoft should have done more testing to ensure that dual-boot setups could be identified accurately. But also distributions shipping signed bootloaders should make sure that they're updating those and updating the security generation to match, because otherwise they're shipping a vector that can be used to attack other operating systems and that's kind of a violation of the social contract around all of this.

It's unfortunate that the victims here are largely end users faced with a system that suddenly refuses to boot the OS they want to boot. That should never happen. I don't think asking arbitrary end users whether they want secure boot updates is likely to result in good outcomes, and while I vaguely tend towards UEFI Secure Boot not being something that benefits most end users it's also a thing you really don't want to discover you want after the fact so I have sympathy for it being default on, so I do sympathise with Microsoft's choices here, other than the failed attempt to avoid the update on dual boot systems.

Anyway. I was extremely involved in the implementation of this for Linux back in 2012 and wrote the first prototype of Shim (which is now a massively better bootloader maintained by a wider set of people and that I haven't touched in years), so if you want to blame an individual please do feel free to blame me. This is something that shouldn't have happened, and unless you're either Microsoft or a Linux distribution it's not your fault. I'm sorry.

Release 0.6.37 of the digest package arrived at CRAN today and has also been uploaded to Debian. digest creates hash digests of arbitrary R objects. It can use a number different hashing algorithms (md5, sha-1, sha-256, sha-512, crc32, xxhash32, xxhash64, murmur32, spookyhash, blake3,crc32c, xxh3_64 and xxh3_128), and enables easy comparison of (potentially large and nested) R language objects as it relies on the native serialization in R. It is a mature and widely-used package (with 70.8 million downloads just on the partial cloud mirrors of CRAN which keep logs) as many tasks may involve caching of objects for which it provides convenient general-purpose hash key generation to quickly identify the various objects. This release updates one of the different hashing source functions which, to remain close to their upstream, used Free() and Calloc() (uppercased to use the R allocator) but not the prefixed stricter versions R_Free() and R_Calloc(). R will switch to enforcing these in the next release next year. Kevin had noticed (while doing some other testing) that this now fails under R-devel (with a switch set), and prepares a very nice and clean PR to take care of it. As of today, CRAN is now sending please fix, or else notes so it was a good time to send this to CRAN. We also updated some remaining http URLs in the README.md to https, and switched to Author/Maintainer field to the now also mandatory Authors@R. My CRANberries provides a summary of changes to the previous version. For questions or comments use the issue tracker off the GitHub repo. For documentation (including the changelog) see the documentation site. If you like this or other open-source work I do, you can now sponsor me at GitHub.

For many years, I have been using the dlvr.it service to echo my online activity to where more people can follow it. Namely, I write in the following sources:

• My blog (where this content is being posted to) RSS
• Mostly academic publications I send to my university s repository (including conference presentations and the like) RSS
• Videos posted to my YouTube channel (mostly my classes but some other material as well) RSS

Via dlvr.it s services, all those posts are echoed to Gwolfwolf in X (Twitter) and to the Gunnarwolfi page in Facebook. I use neither platform as a human (that is, I never log in there). Anyway, dlvr.it sent me a mail stating they would be soon (as in, the next few weeks) cutting their free tier. And, although I value their services and am thankfulfor their value so far, I am not going to pay for my personal stuff to be reposted to social media. So, this post s mission is twofold:

1. If you follow me via any of those media, you will soon not be following me anymore
2. If you know of any service that would fill the space left by dlvr.it, I will be very grateful. Extra gratefulness points if the option you suggest is able to post to accounts in less-propietary media (i.e. the Fediverse). Please tell me by mail (gwolf@gwolf.org).

Oh! Forgot to mention: Of course, my blog will continue to be appear in Planet Debian, Blograf a, and any decent aggregator that consumes my RSS.

A new maintenance release of RcppEigen is now on CRAN, and will go to Debian shortly as usual. Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms. A very recent change in the development version of R (aka r-devel ) expanded the set of declared BLAS and LAPACK functions (and I tooted approvingly about it as well). It turns out that the xerbla() declaration there (which, as usual for R and as discussed in Writing R Extensions, defines the new optional character length entry for a char vector) conflicts with one in the blas.h header in Eigen upsetting the compilation of just one reverse-dependency. So CRAN, as they so often (and quietly) do in these cases, gave us a friendly and concise heads-up and asked for a change so we complied, did the usual reverse-dependency check of the other 400+ packages using RcppEigen and produced the new release which was injected into the repository during the current summer break. The complete NEWS file entry follows.

Changes in RcppEigen version 0.3.4.0.1 (2024-08-14)

• Conditionally comment-out xerbla in blas.h as it is now providedd by R-devel albeit with FC_LEN_T (per a CRAN request)
• Minor package updates (continuous integration, badges)

Courtesy of CRANberries, there is also a diffstat report for the most recent release. If you like this or other open-source work I do, you can sponsor me at GitHub.

Electric Car A while ago I got my hands on an electric car - after not having owned a car for most of my life (there really is not much need here). It wasn t planned nor a goal of mine, but it kind of came out of talks with my boss , so now it s there. Due to some special rules in the german tax system it turns out really cheap for me - it comes from the company, which allows personal use. So I have to pay taxes on the value of it plus whichever amount of kilometers I have to drive to work. And the latter is what is good for me - I have homeoffice in my contract, so no drive to work, except maybe once a year for something. So no regular trip to calculate, only if I ever really have to do a trip to the office. And it being an electric car, running costs are also cheap. Way below the outdated tech that needs gas to run, is annoyingly loud and stinks.

The car In the past I used either car sharing or renting a car when I needed one, depending on what I actually needed. Last times renting I already tried electric variants, so I could compare this with. What I have now is a Citroen e-Berlingo XL from 2023 (so not the latest change from 2024), which is on the huge size for space, but small for battery. It has 7 seats (though I have the last 2 currently taken out, no daily need) and more storage space than I need even on a vacation trip. The engine (or well, it s battery) is on the small side - a capacity of 50 kWh means it only has 278km reach according to WLTP. That actually is a good bit less - as usual, those numbers are lying for the producer. Turns out that on highways in a more realistic mode than WLTP (read: real driving) it s somewhat around 120km before one wants a charger again. But, looking around, at least in Germany that is not a big problem, there are more than enough chargers available.

Driving Actually driving experience is good. It sure is a huge car (4.7m long, 1.85m high/wide) and feels more like driving a (small) bus, but it is easy to handle. Maximum speed is limited (or the small battery would suck even more) to 135km/h, but that is more than enough. Even on german highways. Did my vacation trip with cruise control set to 115km/h and very few times only went above that manually. Real relaxed driving that was.

Vacation trip So we had a vacation just recently, and instead of renting a car for the trip we, of course, wanted to take the e-Berlingo. Distance was about double what the car can (realistically!) do, so one charging stop in the middle somewhere was a must. Not having had to charge on highways yet - and entirely new with this car - that made for a bit of nervousness, but it all turned out really good. There are really nice tools like ABRP to plan your trip including charging, which can take live data of availability of charging points into the planning. And it turned out nice - we reached our planned charging point and found a long queue of cars waiting. But turns out it was all those poor folks that need actual gasoline for their outdated combustion engines. The charging points for EV cars still had enough free space, so we could bypass the queue and directly start charging. We also did not need to repark the car after just a few minutes, we could directly start our break. With a charging time of approx. 30 minutes using the fast charger, such a break is long enough to get enough energy for the next part of the trip and short enough to not be annoying.

Charging prices At home it depends. If one has some photovoltaic system to get power, charging is basically free. If not it depends on whichever contract one has, costs will be somewhat between 0 and ~30cent per kWh. Not much, and way below gasoline costs. Outside, using a fast charger, prices vary depending on where you charge - and with what charging card. Prices between 40 and 70cent / kWh, and the same charging point can vary, just from the card one uses. That is a thing that the EU could actually go and better regulate, similar to the phone regulations it took. Still, the costs are still way below gasoline.

Charging cards There is a huge amount of different providers available, and all do their own things in pricing and how one can use them. They do have standards (say, the plugs are standardized, by now the way to start charging also), and that enables roaming (use a charging card of one provider at a charging point of another), but other than that, it seems to be random. That is - if you use card A on a charging point of Provider B you may pay 0.49cents, if you use card C on the same point, it may charge you 0.79cents. And card D isn t taken at all. Some (the newer ones) you can pay directly by credit card, many you can t. Some may allow paypal or Google/Apple Pay. So in the end you need more than just one charging card - I collected 8 free ones by now - just to be sure you can find a combination that isn t hugely overpriced.

Pain (The Soft Moon Remix) by Boy Harsher ¹ In mid-June I picked up an unknown infection in my left ankle which turned out to be antibiotic resistant. The infection caused cellulitis. After five weeks of trial and error and treatment, the infection is beaten but I am still recovering from the cellulitis. I don t know how long it will take to be fully recovered, nor how long before I can be useful again: I m currently off work (and thus off my open source and other commitments too). Hopefully soon! That s why I ve been quiet.

Another loss last week of a friend. I am staying strong and working through it. A big thank you to all of you that have donated to my car fund, I still have a long way to go. I am not above getting a cheap old car, but we live in sand dunes so it must be a cheap old car with 4 4 to get to my property. A vehicle is necessary as we are 50 miles away from staples such as food and water. We also have 2 funerals to attend. Please consider a donation if my work is useful to you. https://gofund.me/1e784e74 All of my work is currently unpaid work, as I am between contracts. Thank you for your consideration.

Like each month, have a look at the work funded by Freexian s Debian LTS offering.

Debian LTS contributors In July, 13 contributors have been paid to work on Debian LTS, their reports are available:

• Bastien Roucari s did 20.0h (out of 20.0h assigned).
• Chris Lamb did 18.0h (out of 18.0h assigned).
• Daniel Leidert did 5.0h (out of 4.0h assigned and 6.0h from previous period), thus carrying over 5.0h to the next month.
• Guilhem Moulin did 8.75h (out of 4.5h assigned and 15.5h from previous period), thus carrying over 11.25h to the next month.
• Lee Garrett did 51.5h (out of 10.5h assigned and 43.0h from previous period), thus carrying over 2.0h to the next month.
• Lucas Kanashiro did 5.0h (out of 5.0h assigned and 15.0h from previous period), thus carrying over 15.0h to the next month.
• Markus Koschany did 40.0h (out of 40.0h assigned).

• Thorsten Alteholz did 11.0h (out of 11.0h assigned).

Evolution of the situation In July, we have released 1 DLA. August will be the month that Debian 11 makes the transition to LTS. Our contributors have already been hard at work with preparatorty tasks and also with making contributions to packages in Debian 11 in close collaboration with the Debian security team and package maintainers. As a result, users and sponsors should not observe any especially notable differences as the transition occurs. While only one DLA was released in July (as a result of the transitional state of Debian 11 bullseye ), there were some notable highlights. LTS contributor Guilhem Moulin prepared an update of libvirt for Debian 11 (in collaboration with the Old-Stable Release Managers and the Debian Security Team) to fix a number of outstanding CVEs which did not rise to the level of a DSA by the Debian Security Team. The update prepared by Guilhem will be included in Debian 11 as part of the final point release at the end of August, one of the final transition steps by the Release Managers as Debian 11 moves entirely to the LTS Team s responsibility. Notable work was also undertaken by contributors Lee Garrett (fixes on the ansible test suite and a bullseye update), Lucas Kanashiro (Rust toolchain, utilized by the clamav, firefox-esr, and thunderbird packages), and Sylvain Beucler (fixes on the ruby2.5/2.7 test suites and CI infrastructure), which will help improve the quality of updates produced during the next LTS cycle. June was the final month of LTS for Debian 10 (as announced on the debian-lts-announce mailing list). No additional Debian 10 security updates will be made available on security.debian.org. However, Freexian and its team of paid Debian contributors will continue to maintain Debian 10 going forward for customers of the Extended LTS offer. Subscribe right away if you still have Debian 10 systems which must be kept secure (and which cannot yet be upgraded).

Debian Contributions: 2024-07 Contributing to Debian is part of Freexian s mission. This article covers the latest achievements of Freexian and their collaborators. All of this is made possible by organizations subscribing to our Long Term Support contracts and consulting services.

autopkgtest/Incus build streamlining, by Colin Watson Colin contributed a change to allow maintaining Incus container and VM images in parallel. Both of these are useful (containers are faster, but some tests need full machine isolation), and the build tools previously didn t handle that very well. This isn t yet in unstable, but once it is, keeping both flavours of unstable images up to date will be a simple matter of running this regularly:

RELEASE=sid autopkgtest-build-incus images:debian/trixie
RELEASE=sid autopkgtest-build-incus --vm images:debian/trixie

Linux live-patching, by Santiago Ruano Rinc n In collaboration with Emmanuel Arias, Santiago continued the work on the support for applying security fixes to the Linux kernel in Debian, without the need to reboot the machine. As mentioned in the previous month report, kpatch 0.9.9-1 (and 0.9.9-2 afterwards) was uploaded to unstable in July, closing the Intent to Salvage (ITS) bug. With this upload, the remaining RC bugs were solved, and kpatch was able to transition to Debian testing recently. Kpatch is expected to be an important component in the live-patching support, since it makes it easy to build a patch as a kernel module. Emmanuel and Santiago continued to work on the design for Linux live-patching and presented the current status in the DebConf24 presentation.

Salsa CI, by Santiago Ruano Rinc n To be able to add RISC-V support and to avoid using tools not packaged in Debian (See #331), the Salsa CI pipeline first needed to move away from kaniko to build the images used by the pipeline. Santiago created a merge request to use buildah instead, and it was merged last month. Santiago also prepared a couple of more MRs related to how the images are built: initial RISC-V support, that should be merged after improving how built images are tested. The switch to buildah introduced a regression in the work-in-progress MR that adds new build image so the build job can run sbuild. Santiago hopes to address this regression and continue with the sbuild-related MRs in August. Additionally, Santiago also contributed to the install docker-cli instead of docker.io in the piuparts image MR, and reviewed others such as reprotest: Add append-build-command option, fix failure at manual pipeline run when leaving RELEASE variable empty and Fix image not found error on image building stage.

Python 3.13 Betas, by Stefano Rivera As Python 3.13 is approaching the first release, Stefano has been uploading the beta releases to Debian unstable. Most of these have uncovered small bugs that needed to be investigated and fixed. Stefano also took the time to review the current patch set against cPython in Debian. Python 3.13 isn t marked as a supported Python release in Debian s Python tooling, yet, so nothing has been built against it, yet. Now that the Python 3.12 transition has completed, the next task will be to start trying to build Debian s Python module packages against Python 3.13, to estimate the work required to transition to 3.13 in unstable.

Miscellaneous contributions

• Carles Pina updated the packages python-asyncclick, python-pyaarlo and prepared updates for python-ring-doorbell and simplemonitor.
• Carles Pina updated (reviewing or translating) Catalan translations for adduser, apt-listchanges, debconf and shadow.
• Colin merged OpenSSH 9.8, and prepared a corresponding release note for DSA support now being disabled. This version included some substantial changes to split the server into a listener binary and a per-session binary, and those required some corresponding changes in the GSS-API key exchange patch. Sorting out the details of this and getting it to work again took some time.
• Colin upgraded 11 Python packages to new upstream versions, and modernized the build process and/or added non-superficial autopkgtests to several more.
• Rapha l Hertzog tweaked tracker.debian.org s debci task to work around changes in the JSON output. He also improved tracker.debian.org s ability to detect bounces due to spam to avoid unsubscribing emails that are not broken, but that are better than Debian at rejecting spam.
• Helmut Grohne monitored the /usr-move transition with few incidents. A notable one is that some systems have ended up with aliasing links that don t match the ones installed by base-files which could lead to an unpack error from dpkg. This is now prevented by having base-files.preinst error out.
• Helmut investigated toolchain bootstrap failures with gcc-14 in rebootstrap but would only discover the cause in August.
• Helmut sent a MR for the cross-exe-wrapper requested by Simon McVittie for gobject-introspection. It is a way of conditionally requesting qemu-user when emulation is required for execution during cross compilation.
• Helmut sent three patches for cross build failures.
• Thorsten Alteholz uploaded packages lprint and magicfilter to fix RC-bugs that appeared due to the introduction of gcc-14.
• Santiago continued to work on activities related to the DebConf24 Content Team, including reviewing the schedule and handling updates on it.
• Santiago worked on preparations for the DebConf25, to be held in Brest, France, next year. A video of the BoF presented during DebConf24 can be found here.
• Stefano worked on preparations for DebConf24, and helped to run the event.

Vienna - the capital of Austria - is one of the most visited cities in the world, popular for its rich history, gardens, and cafes, along with well-known artists like Beethoven, Mozart, G del, and Freud. It has also been consistently ranked as the most livable city in the world. For these reasons, I was elated when my friend Snehal invited me last year to visit Vienna for a few days. We included Christmas and New Year s Eve in my itinerary due to the city s popular Christmas markets and lively events. The festive season also ensured that Snehal had some days off for sightseeing. Indians require a visa to visit Austria. Since the travel dates were near, I rushed to book an appointment online with VFS Global in Delhi, and quickly arranged the required documents. However, at VFS, I found out that I had applied in the wrong appointment category (tourist), which depends on the purpose of the visit, and that my travel dates do not allow enough time for visa authorities to make a decision. Apparently, even if you plan to stay only for a part of the trip with the host, you need to apply under the category Visiting Friends and Family . Thus, I had to book another appointment under this category, and took the opportunity to shift my travel dates to allow at least 15 business days for the visa application to be processed, removing Christmas and New Year s Eve from my itinerary. The process went smoothly, and my visa application was submitted by VFS. For reference, here s a list of documents I submitted -

• VFS appointment letter
• Duly-filled visa application form
• Original passport
• Copy of passport
• 1 photograph
• My 6 months bank account statement
• Cover letter
• Consent form (that visa processing will take up to 15 business days)
• Snehal s job contract
• My work contract
• Rent contract of Snehal
• Residence permit of Snehal
• A copy of Snehal s passport
• Invitation letter from Snehal
• Return flight ticket reservations
• Travel insurance for the intended travel dates

The following charges were collected from me.

Service Description	Amount (Indian Rupees)
Cash Handling Charge - SAC Code: (SAC:998599)	0
VFS Fee - India - SAC Code: (SAC:998599)	1,820
VISA Fee - India - SAC Code:	7,280
Convenience Fee - SAC Code: (SAC:998599)	182
Courier Service - SAC Code: (SAC:998599)	728
Courier Assurance - SAC Code: (SAC:998599)	182
Total	10,192

I later learned that the courier charges (728 INR) and the courier assurance charges (182 INR) mentioned above were optional. However, VFS didn t ask whether I wanted to include them. When the emabssy is done processing your application, it will send your passport back to VFS, from where you can either collect it yourself or get it couriered back home, which requires you to pay courier charges. However, courier assurance charges do not add any value as VFS cannot assure anything about courier and I suggest you get them removed. My visa application was submitted on the 21st of December 2023. A few days later, on the 29th of December 2023, I received an email from the Austrian embassy asking me to submit an additional document -

Subject: AUSTRIAN VISA APPLICATION - AMENDMENT REQUEST: Ravi Dwivedi VIS 4331 Dear Applicant, On 22.12.2023 your application for Visa C was registered at the Embassy. You are requested to kindly send the scanned copies of the following documents via email to the Embassy or submit the documents at the nearest VFS centre, for further processing of your application:

• Kindly submit Electronic letter of guarantee EVE- Elektronische Verpflichtungserkl rung obtained from the Fremdenpolizeibeh rde of the sponsor s district in Austria. Once your host company/inviting company has obtained the EVE, please share the reference number (starting from DEL_____) received from the authorities, with the Embassy.

Kindly Note: It is in your own interest to fulfil the requirements as indicated above and submit the missing documents within 14 days of the receipt of this email. Otherwise a decision will be taken based on the documentation available. Sie werden in Ihrem Interesse ersucht, die gekennzeichneten M ngel so schnell wie m glich zu beheben bzw. fehlende Unterlagen umgehend nachzureichen, um die weitere Bearbeitung des Antrages zu erm glichen. Sollten Sie innerhalb 14 Tagen die gekennzeichneten M ngel nicht beheben bzw. die fehlenden Unterlagen nicht nachreichen, wird ber den vorliegenden Antrag ohne diese Unterlagen bzw. M ngelbehebung entschieden. Austrian Embassy New Delhi R.J/ Consular Section +91 11 2419 2700 EP-13, Chandragupta Marg, Chanakyapuri, New Delhi 110 021, India bmeia.gv.at/botschaft/new-delhi facebook.at/AustrianEmbassyNewDelhihttp://www.facebook.at/AustrianEmbassyNewDelhi twitter.com/MFA_Austriahttp://www.twitter.com/MFA_Austria [refocus1][Signatur_V+30]https://www.bmeia.gv.at/en/european-foreign-policy/foreign-trade/refocus-austria/[Logo_AT_IN_22px]

I misunderstood the required document (the EVE) to be a scanned copy of the letter of guarantee form signed by Snehal, and responded by attaching it. Upon researching, Snehal determined that the document is an electronic letter of guarantee, and is supposed to be obtained at a local police station in Vienna. He visited a police station the next day and had a hard time conversing due to the language barrier (German is the common language in Austria, whereas Snehal speaks English). That day was a weekend, so he took an appointment for Monday, but in the meantime the embassy had finished processing my visa. My visa was denied, and the refusal letter stated:

The Austrian embassy in Delhi examined your application; the visa has been refused. The decision is based on the following reason(s):

• The information submitted regarding the justification for the purpose and conditions of the intended stay was not reliable.
• There are reasonable doubts as to your intention to leave the territory of the Member States before the expiry of the visa.

Other remarks: You have been given an amendment request, which you have failed to fulfil, or have only fulfilled inadequately, within the deadline set. You are a first-time traveller. The social and economic roots with the home country are not evident. The return from Schengen territory does therefore not seem to be certain.

I could have reapplied after obtaining the EVE, but I didn t because I found the following line

The social and economic roots with the home country are not evident.

offensive for someone who was born and raised in India, got the impression that the absence of electronic guarantee letter was not the only reason behind the refusal, had already wasted 12,000 INR on this application, and my friend s stay in Austria was uncertain after January. In fact, my friend soon returned to India. To summarize -

1. If you are visiting a host, then the category of appointment at VFS must be Visiting Friends and Family rather than Tourist .
2. VFS charged me for courier assurance, which is an optional service. Make sure to get these removed from your bill.
3. Neither my travel agent nor the VFS application center mentioned the EVE.
4. While the required documents list from the VFS website does mention it in point 6, it leads to a dead link.
5. Snehal informed me that a mere two months ago, his wife s visa was approved without an EVE. This hints at inconsistency in processing of applications, even those under identical categories.

Such incidents are a waste of time and money for applicants, and an embarrassment to VFS and the Austrian visa authorities. I suggest that the Austrian visa authorities fix that URL, and provide instructions for hosts to obtain the EVE. Credits to Snehal and Contrapunctus for editing, Badri for proofreading.

On Saturday 3 August 2024, the annual Debian Developers and Contributors Conference came to a close. Over 339 attendees representing 48 countries from around the world came together for a combined 108 events made up of more than 50 Talks and Discussions, 37 Birds of a Feather (BoF informal meeting between developers and users) sessions, 12 workshops, and activities in support of furthering our distribution and free software (25 patches submitted to the Linux kernel), learning from our mentors and peers, building our community, and having a bit of fun. The conference was preceded by the annual DebCamp hacking session held July 21st through July 27th where Debian Developers and Contributors convened to focus on their Individual Debian-related projects or work in team sprints geared toward in-person collaboration in developing Debian. This year featured a BootCamp that was held for newcomers with a GPG Workshop and a focus on Introduction to creating .deb files (Debian packaging) staged by a team of dedicated mentors who shared hands-on experience in Debian and offered a deeper understanding of how to work in and contribute to the community. The actual Debian Developers Conference started on Sunday July 28 2024. In addition to the traditional 'Bits from the DPL' talk, the continuous key-signing party, lightning talks and the announcement of next year's DebConf25, there were several update sessions shared by internal projects and teams. Many of the hosted discussion sessions were presented by our technical core teams with the usual and useful meet the Technical Committee and the ftpteam and a set of BoFs about packaging policy and Debian infrastructure, including talk about APT and Debian Installer and an overview about the first eleven years of Reproducible Builds. Internationalization and localization have been subject of several talks. The Python, Perl, Ruby, and Go programming language teams, as well as Med team, also shared updates on their work and efforts. More than fifteen BoFs and talks about community, diversity and local outreach highlighted the work of various team involved in the social aspect of our community. This year again, Debian Brazil shared strategy and action to attract and retain new contributors and members and opportunities both in Debian and F/OSS. The schedule was updated each day with planned and ad-hoc activities introduced by attendees over the course of the conference. Several traditional activities took place: a job fair, a poetry performance, the traditional Cheese and Wine party, the group photos and the Day Trips. For those who were not able to attend, most of the talks and sessions were broadcast live and recorded and the videos made available through a link in their summary in the schedule. Almost all of the sessions facilitated remote participation via IRC messaging apps or online collaborative text documents which allowed remote attendees to 'be in the room' to ask questions or share comments with the speaker or assembled audience. DebConf24 saw over 6.8 TiB (4.3 TiB in 2023) of data streamed, 91.25 hours (55 in 2023) of scheduled talks, 20 network access points, 1.6 km fibers (1 broken fiber...) and 2.2 km UTP cable deployed, more than 20 country Geoip viewers, 354 T-shirts, 3 day trips, and up to 200 meals planned per day. All of these events, activities, conversations, and streams coupled with our love, interest, and participation in Debian and F/OSS certainly made this conference an overall success both here in Busan, South Korea and online around the world. The DebConf24 website will remain active for archival purposes and will continue to offer links to the presentations and videos of talks and events. Next year, DebConf25 will be held in Brest, France, from Monday, July 7 to Monday, July 21, 2025. As tradition follows before the next DebConf the local organizers in France will start the conference activities with DebCamp with particular focus on individual and team work towards improving the distribution. DebConf is committed to a safe and welcome environment for all participants. See the web page about the Code of Conduct in DebConf24 website for more details on this. Debian thanks the commitment of numerous sponsors to support DebConf24, particularly our Platinum Sponsors: Infomaniak, Proxmox, and Wind River. We also wish to thank our Video and Infrastructure teams, the DebConf24 and DebConf committees, our host nation of South Korea, and each and every person who helped contribute to this event and to Debian overall.

FTP master This month I accepted 502 and rejected 40 packages. The overall number of packages that got accepted was 515. In case you want to upload dozens of packages, it would be nice to give some heads-up before. It is kind of a shock to see a full NEW queue in the morning, though it was much shorter in the evening before. Debian LTS This was my hundred-twenty-first month that I did some work for the Debian LTS initiative, started by Raphael Hertzog at Freexian.

• [#1074439] bookworm-pu: cups 2.4.2-3+deb12u7 has been marked for accept

This month I finished the new version of tiff for Bullseye (and Bookworm). The upload will follow, when Bullseye has been handed over to the LTS team in August. Last but not least I attended the monthly LTS/ELTS meeting. Debian ELTS This month was the seventy-second ELTS month. During my allocated time I uploaded or worked on:

• [ELA-1126-1-1]exim4 security update for one CVE. This was the delayed ELA I mentioned in my last report.
• [ELA-1144-1-1]exim4 security update for one CVE to fix parsing of multiline RFC 2231 header filenames in Stretch and Buster. Jessie was not affected by this issue.
• Uploaded new versions of tiff for Jessie and Stretch that got stuck in the autopkgtests.

For whatever reason, I had trouble with the CI again. The new tiff package wanted to run the autopkgtest of cups but never did it. So the corresponding ELA will appear only in August. I also continued to work on an update for libvirt. There really is a reason why some packages don t get much attention. Nevertheless someone has to take care of them. I also did a week of FD and attended the LTS/ELTS meeting. Debian Printing This month I uploaded

• lprint to fix a /usr-move issue
• magicfilter to fix a gcc14 issue

This work is generously funded by Freexian! Debian Astro This month I uploaded a new upstream or bugfix version of:

• libplayerone to fix a /usr-move issue
• libsbig to fix a /usr-move issue
• libfli to fix a /usr-move issue
• libfishcamp to fix a /usr-move issue

Debian IoT This month I uploaded new upstream or bugfix versions of:

• pyicloud to update dependencies

Debian Mobcom This month I uploaded

• libsmpp34 to fix a gcc14 issue

The following packages have been prepared by the GSoC student Nathan:

• osmo-trx
• osmo-pcu
• libosmocore (another new upstream version)

misc This month I uploaded new upstream or bugfix versions of:

• meep to add autopkgtest
• meep-mpi-default to add autopkgtest
• meep-openmpi to add autopkgtest
• a56 to fix a gcc14 issue (patch provided by Ben)
• setserial to fix a gcc14 issue
• scheme48 to fix a gcc14 issue
• bottlerocket to fix a gcc14 issue
• uucp to fix a gcc14 issue

Planing A Self Organized Solo Trip You know the movie Queen? The actor Kangana Ranaut plays in that movie the role of Rani Mehra, a 24-year-old Punjabi woman, who was a simple, homely girl that was always reliant on her family. Similar to Rani I too rarely ventured out without my parents and often needed my younger sibling by my side. Inspired by her transformation, I decided it was time to take control of my own story and discover who I truly am.

Trip Requirements

My First Passport The journey began with a significant first step: Obtaining my first passport Never having had one before, I scheduled the nearest available interview date on June 29 2022. This meant traveling to Solapur, a city 309 km from my hometown, accompanied by my father. After successfully completing the interview, I received my passport on July 14 2022.

Select A Country, Booking Flights And Accommodation Excited and ready to embark on my adventure, I planed trip to Albania and booked the flight tickets. Why? I had heard from friends that it was a beautiful European country with beaches and other attractions, and importantly, it didn t require a visa for Indian citizens and was more affordable than other European destinations. Before heading to Albania, I planned a overnight stop in Abu Dhabi with a transit visa, thanks to friend who knew the process for obtaining it. Some of my friends did travel also to Europe at the same time and quite close to my plannings, but that I realized just later the trip.

Day 1, Starting The Experience On July 20, 2022, I started my journey by traveling from Pune, Maharashtra, to Delhi, where my brother lives. He came to see me off at the airport, adding a touch of warmth and support to the beginning of my solo adventure. Upon arriving in Delhi, with my next flight scheduled for July 21, I stayed at a backpacker hostel named Zostel, Paharganj, Delhi to rest. During my stay, I noticed that many travelers at the hostel carried rucksacks, which sparked a desire in me to get one for my own trip to Europe. Up until then, I had always shopped with my mom and had never bought anything on my own. Inspired by the travelers, I set out to find a suitable rucksack. I traveled alone by metro from Paharganj to Rohini to visit a Decathlon store, where I purchased a 50-liter rucksack. This was a significant step in preparing for my European adventure and marked a milestone in my journey of self reliance.

Day 2, Flying To Abu Dhabi The following day, July 21 2024, I had a flight to Abu Dhabi. I spent the night at the hostel to rest before my journey. On the day of the flight, I needed to reach the airport by 3 PM, and a friend kindly came to drop me off. With my rucksack packed and excitement building, I was ready for the next leg of my adventure. When we arrived at the airport, my friend saw me off, marking the start of my international journey. With mom made spices, chutneys, and chilly flakes packed for comfort, I completed my immigration process in about two and a half hours. I then settled at the gate for my flight, feeling a mix of excitement and anxiety as thoughts raced through my mind. To ease my nerves, I struck up a conversation with a man seated nearby who was also traveling to Abu Dhabi for work. He provided helpful information about safety and transportation in Abu Dhabi, which reassured me. With the boarding process complete and my anxiety somewhat eased. I found my window seat on the flight and settled in, excited for the journey ahead. Next to me was a young man from Ranchi(Zarkhand, India), heading to Abu Dhabi for work at a mining factory. We had an engaging conversation about work culture in Abu Dhabi and recruitment from India. Upon arriving in Abu Dhabi, I completed my transit, collected my luggage, and began finding my way to the hotel Premier Inn AbuDhabi, which was in the airport area. To my surprise, I ran into the same man from the flight, now in a cab. He kindly offered to drop me at my hotel, which I gladly accepted since navigating an unfamiliar city with a short acquaintance felt safer. At the hotel gate, he asked if I had local currency (Dirhams) for payment, as sometimes online transactions can fail. That hadn t crossed my mind, and I realized I might be left stranded if a transaction failed. Recognizing his help as a godsend, I asked if he could lend me some Dirhams, promising to transfer the amount later. He kindly assured me to pay him back once I reached the hotel room. With that relief, I checked into the hotel, feeling deeply grateful for the unexpected assistance and transferred the money to him after getting to my room.

Day 3, Flying And Arrive In Tirana Once in the hotel room, I found it hard to sleep, anxious about waking up on time for my flight. I set an alarm to wake up early, but my subconscious mind kept me alert, and I woke up before the alarm went off. I got freshened up and went down for breakfast, where I found some vegetarian options like Idli-Sambar and bread with butter, along with some morning tea. After breakfast, I headed back to the airport, ready to catch my flight to my final destination: Tirana, Albania. I reached Tirana, Albania after a six hours flight, feeling exhausted and I was suffering from a headache. The air pressure had blocked my ears, and jet lag added to my fatigue. After collecting my checked luggage, I headed to the first ATM machine at the airport. Struggling to insert my card, I asked a nearby gentleman for help. He tried his best, but my card got stuck inside the machine. Panic set in as I worried about how I would survive without money. Taking a deep breath, I found an airport employee and explained the situation. The gentleman stayed with me, offering support and repeatedly apologizing for his mistake. However, it wasn t his fault, the ATM was out of order, which I hadn t noticed. My focus was solely on retrieving my ATM card. The airport employee worked diligently, using a hairpin to carefully extract my card. Finally, the card was freed, and I felt an immense sense of relief, grateful for the help of these kind strangers. I used another ATM, successfully withdrew money, and then went to an airport mobile SIM shop to buy a new SIM card for local internet and connectivity.

Day 4, Arriving In Tirana, Facing Challenges In A Foreign Country I had booked a stay at a backpacker hostel near the city center of Tirana. After sorting out the ATM and SIM card issues, I searched for a bus or any transport to get there. It was quite late, around 8:30 PM, and being in a new city, I was in a hurry. I saw a bus nearly leaving the airport, stopped it, and asked if it went to the city center. They gave me the green flag, so I boarded the airport service bus and reached the city center. Feeling very tired, I discovered that the hostel was about an hour and a half away by walking. Deciding to take a cab, I faced a challenge as the driver couldn t understand my English or accent. Using a mobile translator to convert my address from English to Albanian, I finally communicated my destination to him. With that sorted out, I headed to the Blue Door Backpacker Hostel and arrived around 9 PM, relieved to have finally reached my destination and I checked in. I found my top bunk bed, only to realize I had booked a mixed-gender dormitory. This detail had completely escaped my notice during the booking process. I felt unsure about how to handle the situation. Coincidentally, my experience mirrored what Kangana faced in the movie Queen . Feeling acidic due to an empty stomach and the exhaustion of heavy traveling, I wasn t up to cooking in the hostel s kitchen. I asked the front desk about the nearest restaurant. It was nearly 9:30 PM, and the streets were deserted. To avoid any mishaps like in the movie Queen, I kept my passport securely locked in my bag, ensuring it wouldn t be a victim of theft. Venturing out for dinner, I felt uneasy on the quiet streets. I eventually found a restaurant recommended by the hostel, but the menu was almost entirely non-vegetarian. I struggled to ask about vegetarian options and was uncertain if any dishes contained eggs, as some people consider eggs to be vegetarian. Feeling frustrated and unsure, I left the restaurant without eating. I noticed a nearby grocery store that was about to close and managed to get a few extra minutes to shop. I bought some snacks, wafers, milk, and tea bags (though I couldn t find tea powder to make Indian-style tea). Returning to the hostel, I made do with wafers, cookies, and milk for dinner. That day was incredibly tough for me, I filled with exhaustion and struggle in a new country, I was on the verge of tears . I made a video call home before sleeping on the top bunk bed. It was a new experience for me, sharing a room with both unknown men and women. I kept my passport safe inside my purse and under my pillow while sleeping, staying very conscious about its security.

Day 5, Exploring Nearby Places I woke up the next day at noon. After having some coffee, the hostel management girl asked if I wanted breakfast. She offered curd with cornflakes, which I refused because I don t like curd. Instead, I ordered a pizza from a vegetarian pizza place with her help, and I started feeling better. I met some people in the hostel, some from Syria and others from Italy. I struggled to understand their accents but kept pushing myself to get involved in their discussions. Despite the challenges, I felt more at ease and was slowly adapting to my new environment. I went out from the hostel in the evening to buy some vegetables to cook something. I searched for shops and found some potatoes, tomatoes, and rice. I decided to cook Khichdi, an Indian dish made with rice, and added some chili flakes I brought from home. After preparing my dinner, I ate and then went to sleep again.

Day 6, Tiranas Recent History The next day, I planned to explore the city and visited Bunkart-1, a fascinating museum in a massive underground bunker from the communist era. Originally built as a shelter for Albania s political and military elite, it now offers a unique glimpse into the country s history under Enver Hoxha s oppressive regime. The museum s exhibits include historical artifacts, photographs, and multimedia displays that detail the lives of Albanians during that time. Walking through the dimly lit corridors, I felt the weight of history and gained a deeper understanding of Albania s past.

Day 7-8, Meeting Friends From India The next day, I accidentally met with Chirag, who was returning from the Debian Conference 2022 held in Prizren, Kosovo, and staying at the same hostel. When I encountered him, he was talking on the phone, and I recognized he was Indian by his accent. I introduced myself, and we discovered we had some mutual friends. Chirag told me that our common friend, Raju, was also coming to stay at the hostel the next day. This news made me feel relaxed and happy to have known people around. When Raju arrived, the three of us, Chirag, Raju, and I planned to have dinner at an Indian restaurant and explore Tirana city. I had a great time talking and enjoying their company.

Day 9-10, Meeting More Friends Raju had a ticket to leave soon, so Chirag and I made a plan to visit Shkod r and the nearby Komani Lake for kayaking. We started our journey early in the morning by bus and reached Shkod r. There, we met new friends from the conference, Pavit and Abraham, who were already there. We had dinner together and enjoyed an ice cream treat from Chirag.

Day 12, Kayaking And Say Good Bye To Friends The next day, Pavit and Abraham had a flight back to India, so Chirag and I went to Komani Lake. We had an adventurous time kayaking, even though neither of us knew how to swim. We took a ferry through the backwaters to the island on Komani Lake and enjoyed a fantastic adventure together. After our trip, Chirag returned to Tirana for his flight back to India, leaving me to continue my journey alone.

Day 13, Climbing Rozafa Castel By stopping at Shkod r, I visited Rozafa Castle. Despite the language barrier, as most locals only spoke Albanian, people around me guided me correctly on how to get there. At times, I used applications like Google Translate to communicate. To read signs or hotel menus, I used Google Photos' language converter. I even used the audio converter to understand and speak some basic Albanian phrases. I took a bus from Shkod r to the southern part of Albania, heading to Sarand . The journey lasted about five to six hours, and I had booked a stay at Mona s Hostel. Upon arrival, I met Eliza from America, and we went together to Ksamil Beach, spending a wonderful day there.

Day 14, Vlora Beach: Beach Side Cycling Next, I traveled to Vlor , where I stayed for one day. During my time there, I enjoyed beach side cycling with a cycle provided by the hostel owner and spent some time feeding fish. I also met a fellow traveler from Delhi who had brought along some preserved Indian curry. He kindly shared it with me, which was a welcome change after nearly 15 days without authentic Indian cuisine, except for what I had cooked myself in various hostels.

Day 15-16 Visiting Durress, Travelling Back To Tirana I then visited Durr s, exploring its beautiful beaches, before heading back to Tirana one day before my flight home. On the day of my flight, my alarm didn t go off, and I woke up late at the hostel. In a frantic rush, I packed everything in just five minutes and dashed toward the city center to catch the bus to the airport. If I had been just five minutes later, I would have missed the bus. Thankfully, I managed to stop it just in time and began my journey back home, reflecting on the incredible adventure I had experienced. Fortunately, I wasn t late; I arrived at the airport just in time. After clearing immigration, I boarded my flight, which had a layover in Warsaw, Poland. The journey from Tirana to Warsaw took about two and a half hours, followed by a seven to eight-hour flight from Poland back to India. Once I arrived in Delhi, I returned to Zostel and booked a train ticket to Aurangabad for the next three days.

Backview This trip was an incredible adventure for me. I never imagined I could accomplish something like this, but I did. Meeting diverse people, experiencing different cultures, and learning so much made this journey truly unforgettable. Looking back, I realize how much I ve grown from this experience. Although I may have more opportunities to travel abroad in the future, this trip will always hold a special place in my heart. The memories I made and the incredible people I met along the way are irreplaceable. This experience goes beyond what I can express through this blog or words; it was incredibly precious to me. Every moment of this journey is etched in my memory, and I am grateful for every part of it.

Reproducible Builds Summit 2024 Last month, we were very pleased to announce the upcoming Reproducible Builds Summit, set to take place from September 17th 19th 2024 in Hamburg, Germany. We are thrilled to host the seventh edition of this exciting event, following the success of previous summits in various iconic locations around the world, including Venice, Marrakesh, Paris, Berlin and Athens. Our summits are a unique gathering that brings together attendees from diverse projects, united by a shared vision of advancing the Reproducible Builds effort. During this enriching event, participants will have the opportunity to engage in discussions, establish connections and exchange ideas to drive progress in this vital field. Our aim is to create an inclusive space that fosters collaboration, innovation and problem-solving. If you re interesting in joining us this year, please make sure to read the event page, which has more details about the event and location. We are very much looking forward to seeing many readers of these reports there.

Pulling Linux up by its bootstraps (LWN) In a recent edition of Linux Weekly News, Daroc Alden has written an article on bootstrappable builds. Starting with a brief introduction that

a bootstrappable build is one that builds existing software from scratch for example, building GCC without relying on an existing copy of GCC. In 2023, the Guix project announced that the project had reduced the size of the binary bootstrap seed needed to build its operating system to just 357-bytes not counting the Linux kernel required to run the build process.

The article goes onto to describe that now, the live-bootstrap project has gone a step further and removed the need for an existing kernel at all. and concludes:

The real benefit of bootstrappable builds comes from a few things. Like reproducible builds, they can make users more confident that the binary packages downloaded from a package mirror really do correspond to the open-source project whose source code they can inspect. Bootstrappable builds have also had positive effects on the complexity of building a Linux distribution from scratch [ ]. But most of all, bootstrappable builds are a boon to the longevity of our software ecosystem. It s easy for old software to become unbuildable. By having a well-known, self-contained chain of software that can build itself from a small seed, in a variety of environments, bootstrappable builds can help ensure that today s software is not lost, no matter where the open-source community goes from here

Towards Idempotent Rebuilds? Trisquel developer Simon Josefsson wrote an interesting blog post comparing the output of the .deb files from our tests.reproducible-builds.org testing framework and the ones in the official Debian archive. Following up from a previous post on the reproducibility of Trisquel, Simon notes that typically [the] rebuilds do not match the official packages, even when they say the package is reproducible , Simon correctly identifies that the purpose of [these] rebuilds are not to say anything about the official binary build, instead the purpose is to offer a QA service to maintainers by performing two builds of a package and declaring success if both builds match. However, Simon s post swiftly moves on to announce a new tool called debdistrebuild that performs rebuilds of the difference between two distributions in a GitLab pipeline and displays diffoscope output for further analysis.

AROMA: Automatic Reproduction of Maven Artifacts Mehdi Keshani, Tudor-Gabriel Velican, Gideon Bot and Sebastian Proksch of the Delft University of Technology, Netherlands, have published a new paper in the ACM Software Engineering on a new tool to automatically reproduce Apache Maven artifacts:

Reproducible Central is an initiative that curates a list of reproducible Maven libraries, but the list is limited and challenging to maintain due to manual efforts. [We] investigate the feasibility of automatically finding the source code of a library from its Maven release and recovering information about the original release environment. Our tool, AROMA, can obtain this critical information from the artifact and the source repository through several heuristics and we use the results for reproduction attempts of Maven packages. Overall, our approach achieves an accuracy of up to 99.5% when compared field-by-field to the existing manual approach [and] we reveal that automatic reproducibility is feasible for 23.4% of the Maven packages using AROMA, and 8% of these packages are fully reproducible.

Community updates On our mailing list this month:

• Nichita Morcotilo reached out to the community, first to share their efforts to build reproducible packages cross-platform with a new build tool called rattler-build, noting that as you can imagine, building packages reproducibly on Windows is the hardest challenge (so far!) . Nichita goes onto mention that the Apple ecosystem appears to be using ZERO_AR_DATE over SOURCE_DATE_EPOCH. [ ]
• Roland Clobus announced that the Debian bookworm 12.6 live images are nearly reproducible , with more detail in the post itself and input in the thread from other contributors.
• As reported in last month s report, Pol Dellaiera completed his master thesis on Reproducibility in Software Engineering at the University of Mons, Belgium. This month, Pol announced this on the list with more background info. Since the master thesis sources have been available, it has received some feedback and contributions. As a result, an updated version of the thesis has been published containing those community fixes.
• Daniel Gr ber asked for help in getting the Yosys documentation to build reproducibly, citing issues in inter alia the PDF generation causing differing CreationDate metadata values.
• James Addison continued his long journey towards getting the Sphinx documentation generator to build reproducible documentation. In this thread, James concerns himself with the problem that even when SOURCE_DATE_EPOCH is configured, Sphinx projects that have configured their copyright notices using dynamic elements can produce nonsensical output under some circumstances. James query ended up generating a number of replies.
• Allen gunner Gunner posted a brief update on the progress the core team is making towards introducing a Code of Conduct (CoC) such that it is in place in time for the RB Summit in Hamburg in September . In particular, gunner asks if you are interested in helping with CoC design and development in the weeks ahead, simply email rb-core@lists.reproducible-builds.org and let us know . [ ]

Android Reproducible Builds at IzzyOnDroid with rbtlog On our mailing list, Fay Stegerman announced a new Reproducible Builds collaboration in the Android ecosystem:

We are pleased to announce Reproducible Builds, special client support and more in our repo : a collaboration between various independent interoperable projects: the IzzyOnDroid team, 3rd-party clients Droid-ify & Neo Store, and rbtlog (part of my collection of tools for Android Reproducible Builds) to bring Reproducible Builds to IzzyOnDroid and the wider Android ecosystem.

Extending the Scalability, Flexibility and Responsiveness of Secure Software Update Systems Congratulations to Marina Moore of the New York Tandon School of Engineering who has submitted her PhD thesis on Extending the Scalability, Flexibility and Responsiveness of Secure Software Update Systems. The introduction outlines its contributions to the field:

[S]oftware repositories are a vital component of software development and release, with packages downloaded both for direct use and to use as dependencies for other software. Further, when software is updated due to patched vulnerabilities or new features, it is vital that users are able to see and install this patched version of the software. However, this process of updating software can also be the source of attack. To address these attacks, secure software update systems have been proposed. However, these secure software update systems have seen barriers to widespread adoption. The Update Framework (TUF) was introduced in 2010 to address several attacks on software update systems including repository compromise, rollback attacks, and arbitrary software installation. Despite this, compromises continue to occur, with millions of users impacted by such compromises. My work has addressed substantial challenges to adoption of secure software update systems grounded in an understanding of practical concerns. Work with industry and academic communities provided opportunities to discover challenges, expand adoption, and raise awareness about secure software updates. [ ]

Development news In Debian this month, 12 reviews of Debian packages were added, 13 were updated and 6 were removed this month adding to our knowledge about identified issues. A new toolchain issue type was identified as well, specifically ordering_differences_in_pkg_info.
Colin Percival filed a bug against the LLVM compiler noting that building i386 binaries on the i386 architecture is different when building i386 binaries under amd64. The fix was narrowed down to x87 excess precision, which can result in slightly different register choices when the compiler is hosted on x86_64 or i386 and a fix committed. [ ]
Fay Stegerman performed some in-depth research surrounding her apksigcopier tool, after some Android .apk files signed with the latest apksigner could no longer be verified as reproducible. Fay identified the issue as follows:

Since build-tools >= 35.0.0-rc1, backwards-incompatible changes to apksigner break apksigcopier as it now by default forcibly replaces existing alignment padding and changed the default page alignment from 4k to 16k (same as Android Gradle Plugin >= 8.3, so the latter is only an issue when using older AGP). [ ]

She documented multiple available workarounds and filed a bug in Google s issue tracker.
Lastly, diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues. This month, Chris Lamb uploaded version 272 and Mattia Rizzolo uploaded version 273 to Debian, and the following changes were made as well:

• Chris Lamb:
  • Ensure that the convert utility is from ImageMagick version 6.x. The command-line interface has seemingly changed with the 7.x series of ImageMagick. [ ]
  • Factor out version detection in test_jpeg_image. [ ]
  • Correct the import of the identify_version method after a refactoring change in a previous commit. [ ]
  • Move away from using DSA OpenSSH keys in tests as support has been deprecated and removed in OpenSSH version 9.8p1. [ ]
  • Move to assert_diff in the test_openssh_pub_key package. [ ]
  • Update copyright years. [ ]
• Mattia Rizzolo:
  • Add support for ffmpeg version 7.x which adds some extra context to the diff. [ ]
  • Rework the handling of OpenSSH testing of DSA keys if OpenSSH is strictly 9.7, and add an OpenSSH key test with a ed25519-format key [ ][ ][ ]
  • Temporarily disable a few packages that are not available in Debian testing. [ ][ ]
  • Stop ignoring the results of Debian testing in the continuous integration system. [ ]
  • Adjust options in debian/source to make sure not to pack the Python sdist directory into the binary Debian package. [ ]
  • Adjust Lintian overrides. [ ]

Website updates There were a number of improvements made to our website this month, including:

• Bernhard M. Wiedemann updated the SOURCE_DATE_EPOCH page to include instructions on how to create reproducible .zip files from within Python using the zipfile module. [ ]
• Chris Lamb fixed a potential duplicate heading on the Projects page. [ ]
• Fay Stegerman added rbtlog to the Tools page [ ] and IzzyOnDroid to the Projects page [ ], also ensuring that the latter page was always sorted regardless of the ordering within the input data files. [ ]
• Holger Levsen added Linus Nordberg to our global list of contributors [ ] as well as made a number of changes to the page for the upcoming Reproducible Builds summit later this year [ ][ ][ ][ ].
• Mattia Rizzolo updated the Civil Infrastructure Platform logo [ ] and also updated the 2024 summit page [ ][ ].
• Nichita Morcotilo added rattler-build to the Projects page. [ ][ ][ ]
• Pol Dellaiera updated the Academic Publications page, adding two publications. [ ][ ]

Reproducibility testing framework The Reproducible Builds project operates a comprehensive testing framework running primarily at tests.reproducible-builds.org in order to check packages and other artifacts for reproducibility. In July, a number of changes were made by Holger Levsen, including:

• Grant bremner access to the ionos7 node. [ ][ ]
• Perform a dummy change to force update of all jobs. [ ][ ]

In addition, Vagrant Cascadian performed some necessary node maintenance of the underlying build hosts. [ ]

I m finishing typing up this blog entry hours before my last 13 hour leg back home, after I spent 2 weeks in Busan, South Korea for DebCamp24 and DebCamp24. I had a rough year and decided to take it easy this DebConf. So this is the first DebConf in a long time where I didn t give any talks. I mostly caught up on a bit of packaging, worked on DebConf video stuff, attended a few BoFs and talked to people. Overall it was a very good DebConf, which also turned out to be more productive than I expeced it would. In the welcome session on the first day of DebConf, Nicolas Dandrimont mentioned that a benefit of DebConf is that it provides a sort of caffeine for your Debian motivation. I could certainly feel that affect swell as the days went past, and it s nice to be excited about some ideas again that would otherwise be fading.

Recovering DPL It s a bit of a gear shift being DPL for 4 years, and DebConf Committee for nearly 5 years before that, and then being at DebConf while some issue arise (as it always does during a conference). At first I jump into high alert mode, but then I have to remind myself it s not your problem anymore and let others deal with it. It was nice spending a little in-person time with Andreas Tille, our new DPL, we did some more handover and discussed some current issues. I still have a few dozen emails in my DPL inbox that I need to collate and forward to Andreas, I hope to finish all that up by the end of August. During the Bits from the DPL talk, the usual question came up whether Andreas will consider running for DPL again, to which he just responded in a slide Maybe . I think it s a good idea for a DPL to do at least two terms if it all works out for everyone, since it takes a while to get up to speed on everything. Also, having been DPL for four years, I have a lot to say about it, and I think there s a lot we can fix in the role, or at least discuss it. If I had the bandwidth for it I would have scheduled a BoF for it, but I ll very likely do that for the next DebConf instead!

Video team I set up the standby loop for the video streaming setup. We call it loopy, it s a bunch of OBS scenes that provide announcements, shows sponsors, the schedule and some social content. I wrote about it back in 2020, but it s evolved quite a bit since then, so I m probably due to write another blog post with a bunch of updates on it. I hope to organise a video team sprint in Cape Town in the first half of next year, so I ll summarize everything before then.

It would ve been great if we could have some displays in social areas that could show talks, the loop and other content, but we were just too pressed for time for that. This year s DebConf had a very compressed timeline, and there was just too much that had to be done and that had to be figured out on the last minute. This put quite a lot of strain on the organisers, but I was glad to see how, for the most part, most attendees were very sympathetic to some rough edges (but I digress ). I added more of the OBS machine setup to the videoteam s ansible repository, so as of now it just needs an ansible setup and the OBS data and it s good to go. The loopy data is already in the videoteam git repository, so I could probably just add a git pull and create some symlinks in ansible and then that machine can be installed from 0% to 100% by just installing via debian-installer with our ansible hooks. This DebConf I volunteered quite a bit for actual video roles during the conference, something I didn t have much time for in recent DebConfs, and it s been fun, especially in a session or two where nearly none of the other volunteers showed up. Sometimes chaos is just fun :-)

Baekyongee is the university mascot, who s visible throughout the university. So of course we included this four legged whale creature on the loop too!

Packaging I was hoping to do more packaging during DebCamp, but at least it was a non-zero amount:

• Uploaded gdisk 1.0.10-2 to unstable (previously tested effects of adding dh-sequence-movetousr) (Closes: #1073679).
• Worked a bit on bcachefs-tools (updating git to 1.9.4), but has a build failure that I need to look into (we might need a newer bindgen) update: I m probably going to ROM this package soon, it doesn t seem suitable for packaging in Debian.
• Calamares: Tested a fix for encrypted installs, and uploaded it.
• Calamares: Uploaded (3.3.8-1) to backports (at the time of writing it s still in backports-NEW).
• Backport obs-gradient-source for bookworm.
• Did some initial packaging on Cambalache, I ll upload to unstable once wlroots (0.18) hits unstable.
• Pixelorama 1.0 I did some initial packaging for Pixelorama back when we did the MiniDebConf Gaming Edition, but it had a few stoppers back then. Version 1.0 seems to fix all of that, but it depends on Godot 4.2 and we re still on the 3 series in Debian, so I ll upload this once Godot 4.2 hits at least experimental. Godot software/games is otherwise quite easy to run, it s basically just source code / data that is installed and then run via godot-runner (godot3-runner package in Debian).

BoFs Python Team BoF Link to the etherpad / pad archive link and video can be found on the talk page: https://debconf24.debconf.org/talks/31-python-bof/ The session ended up being extended to a second part, since all the issues didn t fit into the first session. I was distracted by too many thing during the Python 3.12 transition (to the point where I thought that 3.11 was still new in Debian), so it was very useful listening to the retrospective of that transition. There was a discussion whether Python 3.13 could still make it to testing in time for freeze, and it seems that there is consensus that it can, although, likely with new experimental features like disabling the global interpreter lock and the just in time compiler disabled. I learned for the first time about the dead batteries project, PEP-0594, which removes ancient modules that have mostly been superseded, from the Python standard library. There was some talk about the process for changing team policy, and a policy discussion on whether we should require autopkgtests as a SHOULD or a MUST for migration to testing. As with many things, the devil is in the details and in my opinion you could go either way and achieve a similar result (the original MUST proposal allowed exceptions which imho made it the same as the SHOULD proposal). There s an idea to do some ongoing remote sprints, like having co-ordinated days for bug squashing / working on stuff together. This is a nice idea and probably a good way to energise the team and also to gain some interest from potential newcomers. Louis-Philipe V ronneau was added as a new team admin and there was some discussion on various Sphinx issues and which Lintian tags might be needed for Python 3.13. If you want to know more, you probably have to watch the videos / read the notes :)

Debian.net BoF Link to the etherpad / pad archive link can be found on the talk page: https://debconf24.debconf.org/talks/37-debiannet-team-bof Debian Developers can set up services on subdomains on debian.net, but a big problem we ve had before was that developers were on their own for hosting those services. This meant that they either hosted it on their DSL/fiber connection at home, paid for the hosting themselves, or hosted it at different services which became an accounting nightmare to claim back the used funds. So, a few of us started the debian.net hosting project (sometimes we just call it debian.net, this is probably a bit of a bug) so that Debian has accounts with cloud providers, and as admins we can create instances there that gets billed directly to Debian. We had an initial rush of services, but requests have slowed down since (not really a bad thing, we don t want lots of spurious requests). Last year we did a census, to check which of the instances were still used, whether they received system updates and to ask whether they are performing backups. It went well and some issues were found along the way, so we ll be doing that again. We also gained two potential volunteers to help run things, which is great. Debian Social BoF Link to the etherpad / pad archive link can be found on the talk page: https://debconf24.debconf.org/talks/34-debiansocial-bof We discussed the services we run, you can view the current state of things at: https://wiki.debian.org/Teams/DebianSocial Pleroma has shown some cracks over the last year or so, and there are some forks that seem promising. At the same time, it might be worth while considering Mastodon too. So we ll do some comparison of features and maintenance and find a way forward. At the time when Pleroma was installed, it was way ahead in terms of moderation features. Pixelfed is doing well and chugging along nicely, we should probably promote it more. Peertube is working well, although we learned that we still don t have all the recent DebConf videos on there. A bunch of other issues should be fixed once we move it to a new machine that we plan to set up. We re removing writefreely and plume. Nice concepts, but it didn t get much traction yet, and no one who signed up for these actually used it, which is fine, some experimentation with services is good and sometimes they prove to be very popular and other times not. The WordPress multisite instance has some mild use, otherwise haven t had any issues. Matrix ended up to be much, much bigger than we thought, both in usage and in its requirements. It s very stateful and remembers discussions for as long as you let it, so it s Postgres database is continuously expanding, this will also be a lot easier to manage once we have this on the new host. Jitsi is also quite popular, but it could probably be on jitsi.debian.net instead (we created this on debian.social during the initial height of COVID-19 where we didn t have the debian.net hosting yet), although in practice it doesn t really matter where it lives. Most of our current challenges will be solved by moving everything to a new big machine that has a few public IPs available for some VMs, so we ll be doing that shortly. Debian Foundation Discussion BoF This was some brainstorming about the future structure of Debian, and what steps might be needed to get there. It s way too big a problem to take on in a BoF, but we made some progress in figuring out some smaller pieces of the larger puzzle. The DPL is going to get in touch with some legal advisors and our trusted organisations so that we can aim to formalise our relationships a bit more by the time it s DebConf again. I also introduced my intention to join the Debian Partners delegation. When I was DPL, I enjoyed talking with external organisations who wanted to help Debian, but helping external organisations help Debian turned out to be too much additional load on the usual DPL roles, so I m pursuing this with the Debian Partners team, more on that some other time. This session wasn t recorded, but if you feel like you missed something, don t worry, all intentions will be communicated and discussed with project members before anything moves forward. There was a strong agreement in the room though that we should push forward on this, and not reach another DebConf where we didn t make progress on formalising Debian s structure more.

Social Conference Dinner

Conference Dinner Photo from Santiago

The conference dinner took place in the university gymnasium. I hope not many people do sports there in the summer, because it got HOT. There was also some interesting observations on the thermodynamics of the attempted cooling solutions, which was amusing. On the plus side, the food was great, the company was good, and the speeches were kept to a minimum, so it was a great conference dinner, even though it was probably cut a bit short due to the heat. Cheese and Wine Cheese and Wine happened on 1 August, which happens to be the date I became a DD at DebConf17 in Montr al seven years before, so this was a nice accidental celebration of my Debiversary :) Since I m running out of time, I ll add some more photos to this post some time after publishing it :P Group Photo As per DebConf tradition, Aigars took the group photo. You can find the high resolution version on Debian s GitLab instance.

Talking Ah yes, talking to people is a big part of DebConf, but I didn t keep track of it very well.

• I mostly listened to Alper a bit about his ideas for his talk about debian installer.
• I talked to Rhonda a bit about ActivityPub and MQTT and whether they could be useful for publicising Debian activity.
• Listened to Gunnar and Julian have a discussion about GPG and APT which was interesting.
• I learned that you can learn Hangul, the Korean alphabet, in about an hour or so (I wish I knew that in all my years of playing StarCraft II).
• We had the usual continuous keysigning party. Besides it s intended function, this is always a good ice breaker and a way to for shy people to meet other shy people.
• and many other fly-by discussions.

Stuff that didn t happen this DebConf

• loo.py A simple Python script that could eventually replace the obs-advanced-scene-switcher sequencer in OBS. It would also be extremely useful if we d ever replace OBS for loopy. I was hoping to have some time to hack on this, and try to recreate the current loopy in loo.py, but didn t have the time.
• toetally This year videoteam had to scramble to get a bunch of resistors to assemble some tally light. Even when assembled, they were a bit troublesome. It would ve been nice to hack on toetally and get something ready for testing, but it mostly relies on having something like a rasbperry pi zero with an attached screen in order to work on further. I ll try to have something ready for the next mini conf though.
• extrepo on debian live I think we should have extrepo installed by default on desktop systems, I meant to start a discussion on this, but perhaps it s just time I go ahead and do it and announce it.
• Live stream to peertube server It would ve been nice to live stream DebConf to PeerTube, but the dependency tree to get this going got a bit too huge. Following our plans discussed in the Debian Social BoF, we should have this safely ready before the next MiniDebConf and should be able to test it there.
• Desktop Egg there was this idea to get a stand-in theme for Debian testing/unstable until the artwork for the next release is finalized (Debian bug: #1038660), I have an idea that I meant to implement months ago, but too many things got in the way. It s based on Juliette Taka s Homeworld theme, and basically transforms the homeworld into an egg. Get it? Something that hasn t hatched yet? I also only recently noticed that we never used the actual homeworld graphics (featuring the world image) in the final bullseye release. lol.

So, another DebConf and another new plush animal. Last but not least, thanks to PKNU for being such a generous and fantastic host to us! See you again at DebConf25 in Brest, France next year!

Debian Download Web Page It's just a very tiny difference, but hopefully a big step forward for our users. Our main download web page (which still uses the URL https://www.debian.org/distrib/) now has the title "Download Debian". Hopefully this will improve the results in the search engines.

A brief history of this web page in time

• 1998: The title "Distribution" was added
• 2002: Title changed to "Getting Debian"
• 2024: Finally changed to "Download Debian"

Here are the screenshots of these three versions. I like that we had a selection menu on the top right corner to select a mirror for downloading in the past. A few days ago I've also removed the info "Internal ISDN cards are unfortunately not supported." from the netinst subpage. Things are moving forward, but slowly.

The Freedesktop.org Specifications directory contains a list of common specifications that have accumulated over the decades and define how common desktop environment functionality works. The specifications are designed to increase interoperability between desktops. Common specifications make the life of both desktop-environment developers and especially application developers (who will almost always want to maximize the amount of Linux DEs their app can run on and behave as expected, to increase their apps target audience) a lot easier. Unfortunately, building the HTML specifications and maintaining the directory of available specs has become a bit of a difficult chore, as the pipeline for building the site has become fairly old and unmaintained (parts of it still depended on Python 2). In order to make my life of maintaining this part of Freedesktop easier, I aimed to carefully modernize the website. I do have bigger plans to maybe eventually restructure the site to make it easier to navigate and not just a plain alphabetical list of specifications, and to integrate it with the Wiki, but in the interest of backwards compatibility and to get anything done in time (rather than taking on a mega-project that can t be finished), I decided to just do the minimum modernization first to get a viable website, and do the rest later. So, long story short: Most Freedesktop specs are written in DocBook XML. Some were plain HTML documents, some were DocBook SGML, a few were plaintext files. To make things easier to maintain, almost every specification is written in DocBook now. This also simplifies the review process and we may be able to switch to something else like AsciiDoc later if we want to. Of course, one could have switched to something else than DocBook, but that would have been a much bigger chore with a lot more broken links, and I did not want this to become an even bigger project than it already was and keep its scope somewhat narrow. DocBook is a markup language for documentation which has been around for a very long time, and therefore has older tooling around it. But fortunately our friends at openSUSE created DAPS (DocBook Authoring and Publishing Suite) as a modern way to render DocBook documents to HTML and other file formats. DAPS is now used to generate all Freedesktop specifications on our website. The website index and the specification revisions are also now defined in structured TOML files, to make them easier to read and to extend. A bunch of specifications that had been missing from the original website are also added to the index and rendered on the website now. Originally, I wanted to put the website live in a temporary location and solicit feedback, especially since some links have changed and not everything may have redirects. However, due to how GitLab Pages worked (and due to me not knowing GitLab CI well enough ) the changes went live before their MR was actually merged. Rather than reverting the change, I decided to keep it (as the old website did not build properly anymore) and to see if anything breaks. So far, no dead links or bad side effects have been observed, but: If you notice any broken link to specifications.fd.o or anything else weird, please file a bug so that we can fix it! Thank you, and I hope you enjoy reading the specifications in better rendering and more coherent look!

Thankfully no tragedies to report this week! I thank each and everyone of you that has donated to my car fund. I still have a ways to go and could use some more help so that we can go to the funeral. https://gofund.me/033eb25d I am between contracts and work packages, so all of my work is currently for free. Thanks for your consideration. Another very busy week getting qt6 updates in Debian, Kubuntu, and KDE snaps. Kubuntu:

• Merkuro and Neochat SRUs have made progress.
• See Debian for the qt6 Plasma / applications work.

Debian:

• qtmpv in NEW
• arianna in NEW
• kamera experimental
• libkdegames experimental
• kdenetwork-filesharing experimental
• xwaylandvideobridge NEW
• futuresql NEW
• kpat WIP
• Tokodon Done, but needs qtmpv to pass NEW
• Gwenview WIP needs kamera, kio-extras
• kio-extras Blocked on kdsoap in which the maintainer is not responding to bug reports or emails. Will likely fork in Kubuntu as our freeze quickly approaches.

KDE Snaps: Updated QT to 6.7.2 which required a rebuild of all our snaps. Also found an issue with mismatched ffmpeg libraries, we have to bundle them for now until versioning issues are resolved. Made new theme snaps for KDE breeze: gtk-theme-breeze, icon-theme-breeze so if you use the plasma theme breeze please install these and run

for PLUG in $(snap connections   grep gtk-common-themes:icon-themes   awk ' print $2 '); do sudo snap connect $ PLUG  icon-theme-breeze:icon-themes; done
for PLUG in $(snap connections   grep gtk-common-themes:gtk-3-themes   awk ' print $2 '); do sudo snap connect $ PLUG  gtk-theme-breeze:gtk-3-themes; done
for PLUG in $(snap connections   grep gtk-common-themes:gtk-2-themes   awk ' print $2 '); do sudo snap connect $ PLUG  gtk-theme-breeze:gtk-2-themes; done

This should resolve most theming issues. We are still waiting for kdeglobals to be merged in snapd to fix colorscheme issues, it is set for next release. I am still working on qt6 themes and working out how to implement them in snaps as they are more complex than gtk themes with shared libraries and file structures. Please note: Please help test the edge snaps so I can promote them to stable.

Dear Debian community, this are my bits from DPL written at my last day at another great DebConf. DebConf attendance At the beginning of July, there was some discussion with the bursary and content team about sponsoring attendees. The discussion continued at DebConf. I do not have much experience with these discussions. My summary is that while there is an honest attempt to be fair to everyone, it did not seem to work for all, and some critical points for future discussion remained. In any case, I'm thankful to the bursary team for doing such a time-draining and tedious job. Popular packages not yet on Salsa at all Otto Kek l inen did some interesting investigation about Popular packages not yet on Salsa at all. I think I might provide some more up to date list soon by some UDD query which considers more recent uploads than the trends data soon. For instance wget was meanwhile moved to Salsa (thanks to No l K the for this). Keep on contacting more teams I kept on contacting teams in July. Despite I managed to contact way less teams than I was hoping I was able to present some conclusions in the Debian Teams exchange BoF and Slide 16/23 of my Bits from the DPL talk. I intend to do further contacts next months. Nominating Jeremy B cha for GNOME Advisory Board I've nominated Jeremy B cha to GNOME Advisory Board. Jeremy has volunteered to represent Debian at GUADEC in Denver. DebCamp / DebConf I attended DebCamp starting from 22 July evening and had a lot of fun with other attendees. As always DebConf is some important event nearly every year for me. I enjoyed Korean food, Korean bath, nature at the costline and other things. I had a small event without video coverage Creating web galleries including maps from a geo-tagged photo collection. At least two attendees of this workshop confirmed success in creating their own web galleries. I used DebCamp and DebConf for several discussions. My main focus was on discussions with FTP master team members Luke Faraone, Sean Whitton, and Utkarsh Gupta. I'm really happy that the four of us absolutely agree on some proposed changes to the structure of the FTP master team, as well as changes that might be fruitful for the work of the FTP master team itself and for Debian developers regarding the processing of new packages. My explicit thanks go to Luke Faraone, who gave a great introduction to FTP master work in their BoF. It was very instructive for the attending developers to understand how the FTP master team checks licenses and copyright and what workflow is used for accepting new packages. In the first days of DebConf, I talked to representatives of DebConf platinum sponsor WindRiver, who announced the derivative eLxr. I warmly welcome this new derivative and look forward to some great cooperation. I also talked to the representative of our gold sponsor, Microsoft. My first own event was the Debian Med BoF. I'd like to repeat that it might not only be interesting for people working in medicine and microbiology but always contains some hints how to work together in a team. As said above I was trying to summarise some first results of my team contacts and got some further input from other teams in the Debian Teams exchange BoF. Finally, I had my Bits from DPL talk. I received positive responses from attendees as well as from remote participants, which makes me quite happy. For those who were not able to join the events on-site or remotely, the videos of all events will be available on the DebConf site soon. I'd like to repeat the explicit need for some volunteers to join the Lintian team. I'd also like to point out the "Tiny tasks" initiative I'd like to start (see below). BTW, if someone might happen to solve my quiz for the background images there is a summary page in my slides which might help to assign every slide to some DebConf. I could assume that if you pool your knowledge you can solve more than just the simple ones. Just let me know if you have some solution. You can add numbers to the rows and letters to the columns and send me: This list provides some additional information for DebConfs I did not attend and when no video stream was available. It also reminds you about the one I uncovered this year and that I used two images from 2001 since I did not have one from 2000. Have fun reassembling good memories. Tiny tasks: Bug of the day As I mentioned in my Bits from DPL talk, I'd like to start a "Tiny tasks" effort within Debian. The first type of tasks will be the Bug of the day initiative. For those who would like to join, please join the corresponding Matrix channel. I'm curious to see how this might work out and am eager to gain some initial experiences with newcomers. I won't be available until next Monday, as I'll start traveling soon and have a family event (which is why I need to leave DebConf today after the formal dinner). Kind regards from DebConf in Busan Andreas.
