  • Backlog grooming
    • Helped finding workarounds for several bugs until we have proper fixes.

Very short week due to PTO. Really not much to report besides catching up on emails and a bit of bug triage.

spec

  • Discussed with @vorlon about FO194 (ā€œLow-priority queue for continuously re-run of autopkgtestā€), and still need to implement the required changes.

curtin

  • Further work to integrate the CI on Github. Sparked some improvements in the integration code.

auto-upgrade-testing

autopkgtest / retry MIR

  • Opened an SRU bug to get retry in {jammy,noble}-updates and be able to promote it to main. Itā€™s not accepted and verified, just needs aging.

autopkgtest-cloud

  • Big bunch of reviews.
  • Worked on easing running a local worker, to simplify development of that part.
  • Started to work on moving away from python3-amqplib in favor of python3-amqp.

apport-retracer

I was off last Thursday and Friday, so this is two weeks worth of updates:

dotnet

  • Attended the weekly .NET partners sync meeting.
  • Bootstrapped .NET 8 on s390x and ppc64el for Ubuntu 22.04 (Jammy Jellyfish).
  • Started the Jammy SRU for s390x and ppc64el enablement (LP: #2080023). The package has been uploaded and is currently in the Jammy unapproved queue.
  • Investigated the current state of the snapcraft dotnet plugin and ways it can be improved.
  • Working on bootstrapping .NET 9 on s390x and ppc64el for the dotnet9 package on Oracular.

Jammy

Noble

  • Worked on mercurial SRUs:
    • LP: #2070443 - Fix critical regression in Mercurial 6.7.x < 6.7.4
    • LP: #2076152 - Fix incompatibility with Python 3.12.5
    • LP: #2081117 - Fix subsequent FTBFS after @racb kindly sponsored for SRU
  • Uploaded SRU for noble u-boot:
    • LP: #2054092 - Enable FIT images
    • Adjusted verification to deal with the fact enabling FIT breaks the source command for classic u-boot scripts
    • Verified SRU operation on two boards

Oracular

  • Awaiting review of rpi-eeprom bump to support CM5 (LP: #2080368)
  • Installer hokey-cokey:
    • Proposed changes to fix missing languages in the Ubuntu Oracular Pi Desktop
    • But as theyā€™re not removed post-install, weā€™re going back to ubiquity
    • Speaking of which, itā€™s broken again (when is ubiquity not broken?)
    • Proposed a merge to fix FTBFS, kindly sponsored by @sil2100
  • Looked at rpi-imager 1.9; weā€™re passed feature freeze so this will be pushed to next cycle
    • New upstream release, thereā€™s quite a bit of work to do
    • Changes to Qt6 (currently unpackaged 6.7, but I suspect that can be pulled back to something earlier)
    • Vendors (almost) all dependencies; this should be undone for deb, kept for the snap
  • Looked at raspi-utils; again, pushed to next cycle as wasnā€™t critical (just ā€œnice to haveā€) for rpi-eeprom bump
    • New upstream release, lots of changes
    • Now split into multiple packages, a subset of which replace legacy libraspberrypi-bin
    • Upgrade story isā€¦ complex!
  • Updated release notes for beta

General

  • Investigated presence of kdump-tools on Pi desktop images with @cpete; not active by default, so weā€™re leaving it there
  • Gave some advice to @r41k0u on building images locally
  • Reviewed PR for ttyAMA slots in core gadget
  • Wrote an application. No, not that sort of applicationā€¦

This week I was mostly stuck on https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/2063365 - it is taking longer than expected. Turns out the fix described at https://lore.kernel.org/all/d90cc093-e3fc-4af4-9a4a-5f4bd9a7cb1f@gmx.net/ is not correct and the problem is somewhere deeper. I have a hunch that the country setting needs to be reset too after a disconnect. I spent most of the week investigating this and going around raspi kernel tooling
