Andrew Cater: 202306101010 - Debian release preparations and boot media testing in Cambridge

We've all met up in Cambridge - so there's an egw_, amacater, kibi who has travelled over to join us, Isy, RattusRattus and Sledge mostly sat round a table. The usual number of laptops, three monitors, Rattus' tower machine.Network running well and we're all ready to go, I think - there's normally a flurry of activity to get things started then a wait for a while for the first images
Coffee and tea at the ready - bacon sandwiches are on the way

[And the build process is under way - and smcv has joined us]

Andy Simpkins: Debian Bullseye Released

Wow. It is 21:49 in the evening here (I am with isy and sledge in Cambridge) and image testing has completed! The images are being signed, and sledge is running through the final steps to push them out to our servers, and from there out onto the mirror and torrent networks to be available for public download.

We have had help testing installation images from the regular team; amacater and schweer. With schweer, as ever, covering the edu images. Thank you. This release we were joined by bitin who kindly ran through a couple of tests of the default netinst image with both UEFI and BIOS based VMs, before joining a release party. Moving onto the live images, linux-fan once again spent time testing i386 images on vintage hardware. Getting a desktop environment to work on a Pentium (4?) machine with 1GiB RAM from a live-image sees the number of desktops that will run in this environment get fewer all the time. Again highvoltage was around to run tests on some of the images.

liz, contributed for the first time indeed raised her first bug report as well. I hope that you had fun thanks for joining us today. smcv, also joined in the testing fun a long time DD is this the first time you have run through image smoke tests on release day? thanks! Many thanks to everyone taking time to test installation and live images. Of cause building and testing images doesn t happen in isolation. There is a huge team that puts together and releases the project that is Debin .
On a release day there are many teams working flat out: dsa, ftp, publicity, release, web, and ourselves as the cd/images team.
But that is just activity on a release day
There are all the other teams that are needed to produce the distribution, who work tirelessly day in, day out. Curating the 1,152,960,944 lines of code in Debian bullseye are over more than 6,208 people!!
Some of the contributors are shown in https://contributors.debian.org/contributors/flat
THANK YOU In the 15 minutes it has taken me to compile this post (many thanks to cnote and jmw for facts and figures they published on debian micronews), the last of the image release process has completed by sledge and that s it. Installation images for Debian 11 Bullseye are out in the big wide world, joining the official archives that became available at 10:35 this morning.

Andrew Cater: How to use jigdo to download media images

I worked with the CD release team over the weekend for the final release of Debian Stretch. One problem: we have media images which we cannot test because the team does not have the hardware. I asked questions on the debian-cd mailing list about the future of these and various other .iso images.

Could we replace some DVDs and larger files with smaller jigdo files so that people can download files to build the DVD locally?

People asked me:
Why jigdo?
Using jigdo

Jigdo uses information from a template file to reconstruct an .iso file by downloading Debian packages from a mirror. The image is checksummed and verified at the end of the complete download. if the download is interrupted, you can import the previously downloaded part of the file.

It's a command line application - the GUI never really happened - but it is fairly easy to use. apt install jigdo-file then find the .jigdo file and .template files that you need for the image from a CD mirror: https://cdimage.debian.org/debian-cd/current/amd64/jigdo-cd/

To build the netinst CD for AMD64, for example: you need the .jigdo file as a minimum: debian-10.4.0-amd64-netinst.jigdo

If you only have this file, jigdo-lite will download the template later but you can save the template in the same directory and save time. The jigdo file is only 25k or so and the template is 4.6M rather than 336M. I copied them into my home directory to build there. The process does not need root permissions.

Run the command jigdo-lite This prompts you for a .jigdo file to use. By default, this uses http to fetch the file from a distant webserver.
(If the files are local, you can use the file:/// syntax.For example: file:///home/amacater/debian-10.4.0-amd64-netinst.jigdo)

jigdo-lite then reads the .jigdo file and outputs some information about the .iso
It offers the chance to reload any failed download, then prompts for a mirror name. The download pulls in small numbers of files at a time, saves to a temporary directory and will checksum the eventual .iso file.

This will work for any larger file including the 16GB .iso distributed only as a .jigdo

For i386 and AMD, the images are bootable when copied to a USB stick. Use dd to write them and verify the copy.
  • Plug in a USB that can be overwritten.
  • Use dmesg as root to work out which device this is.
  • Change to the directory in which you have your .iso image.
  • Write the image to the stick in 4M blocks and display progress with the syntax of the command below (all one line if wrapped).

dd if=debian-10.4.0-amd64-netinst.iso of=/dev/sdX obs=4M oflag=sync status=progress

Andrew Cater: Formal key transitiion to 4096 bit key

Following mini-Debconf and submitting my key to keyring-maint, here's a copy of the note marking the transition. I do retain a copy of the old key: it has not been compromised or revoked (until I'm sure my new key reaches the Debian keyring) and my vote in the GR is validly signed with the old key.

From: "Andrew M.A. Cater"
To: keyring@rt.debian.org

Andrew Cater: Engaged to be married

A heads up to my Debian family - before I get to tell some of my other family :) I'm engaged to a wonderful girl. We've known each other off and on for almost 30 years, having met on the first day at university.

Lots of life has happened in the middle - including Debian - but we're now very happily together again.
