Go

  • golang-defaults has been updated to 1.23. Working on the proposed migration for that.
    • containerd needs patch to build with with Go 1.23. But due to the current ongoing Go libraries transition, containerd/1.6 FTBFS with -proposed. The patch is now integrated in Debian package with new version, will merge the package later.
    • golang-gvisor-gvisor needs a new version to build with Go 1.23. Updated in Debian and synced to Ubuntu.
  • Update Go 1.22.6 & 1.21.13 releases.

imagecraft

  • PR # 53 - Make imagecraft build an image
    • Fixed several bugs to build an image.
    • Also documented how to build an image at the same time.
    • In review.
  • PR # 54 - Add basic spread tests
    • Done and in review.
    • I am discussing a bug in craft-parts preventing the build from working on 20.04 (or in fact any build base too old to have git able to properly a specific clone command)
  • PR #54 - Migrate to craft-application 3.X
    • Needed to properly select the build provider (and specifically multipass)
    • Removing some code (now in the libs) and adapting to new concepts (BuildPlanner, etc.). This kind of things is “safer” to do now that we have basic spread tests.
  • Opened LP #2076320 because the automatic schedule build of the imagecraft snap is not working (probably because the recipe references a external repo)
    • I will trigger rebuilds by hand for now until I know if the LP team plans on fixing this soon or not. If not, I will mirror the repo on LP but I would like to avoid that because it slows down the build of a new snap when pushing to main.

ubuntu-image

  • Providing support to several users
  • Reviewed, added spread tests and merged PR # 239 - snapcraft.yaml: Fix config installation. Thanks @tobhe!
  • Investigated some more LP #2057885
    • The workaround in place is not satisfying our users.
    • We probably need to revert our change andset the gpg homedir in /tmp again.
  • PR # 222 - Run spread tests on noble too
    • Rebased and merged.
  • PR # 240 - Add dosfstools (needed to have mkfs.vfat)
    • Done and merged.
  • PR # 241 - Clean /dev/, /run/, /sys/
    • Done and in review.

distro

  • python-docutils/0.21.2+dfsg-2 proposed-migration: investigated ruby-github-markup blocking python-docutils, but a new Debian upload fixed the issue so just needed to wait for auto-sync and retried autopkgtests. Also retried autopkgtests for snakemake and got them to pass.

dotnet

  • Implemented a notification mechanism using systemd-path that allows the strictly-confined content snaps (.NET Runtime and SDK snaps) to notify the .NET Installer, which sits in a classical snap, whenever they get updated (refreshed) so that the installer can update the .mount systemd units. These units contain version numbers in the path they bind-mount, which is the reason why every update needs a new .mount unit.
  • Working on CI validation tests for the .NET content snaps (canonical/dotnet-content-snaps#6)

Distro

  • I spent a lot of time on py3clean fails when using alternate character set: I wrote a Python script to check all packages in the archive. That script ran over the weekend on the noble package. The tests for the jammy packages are still running.

hardware-installer-testing

  • Refactored and tidied up a fair bit of the repo
  • modified the jenkins jobs for the tests to make them production ready
  • 2 pr’s to add boot steps for new machines in order to boot them from usb

testflinger

  • a couple of small pr’s: one to fix a string formatting issue in some logging, another with a fix to some documentation

autopkgtest-cloud

  • investigation into some issues we had with seed-new-release when opening up autopkgtest for oracular
  • fixed said issue - MP
  • fixed a traceback for one of our juju actions - MP
  • investigating issues with bos03-s390x - proxy issues and issues ssh’ing to units - still ongoing

autopkgtest-cloud

  • MP review for @uralt
  • Some investigation for @ogayot’s issue with python-argcomplete and zsh
  • Opened an RT to officially ask about nested virtualization on arm64 and s390x
  • Tried to dump some metadata about the running test in their log files, but it proved harder than expected. I’ll have to discuss the way forward with the team.
  • Cowboyed a fix for a user page 500 error reported by @mitchdz: the cowboy adds some logging in addition to catching the exception, so that we can understand why the exception is thrown in the first place, and make sure it’s not hiding a real issue. I’ll open the MP with the long term fix once I have more data on this, but so far, nothing appeared.
  • Started working on FO194 about continuously re-running some autopkgtests (like tmpfails or fails ones). This is now in the first round of review.
  • Worked on embedding the autopkgtest-cloud code with a git clone instead of bundled in the charm, to ease the cowboys, updates, and testing branches. I’m currently blocked at the testing stage: my current charm seems blocked on some unrelated error around the apt layer. I might have to do a bit more than just a juju deploy.

autopkgtest

  • Preparing the SRU for autopkgtest/5.37ubuntu4

python-amqplib

MIR retry

  • Opened a MIR for retry, because it’s a new dependency of autopkgtest
