ubuntu-image

  • Created PR to resolve issue with /etc/resolv.conf
  • Reviewed snapd PR for supporting max-revision-assertions and determined that there is nothing to be done in ubuntu-image to support this. All of the information is sourced from existing snap files, so no extra input from u-i is required.
  • Wrote a spec for supporting specifying snap revisions for core and classic builds
  • Began prototyping this revision support - working for core builds
  • Began prototyping fully preseeding snaps in ubuntu-image builds. Spec to come
    • Running into weird cgroups issue that I haven’t figured out yet
  • Investigating snap FTBFS on riscv64
    • Traced this to a bug in core22 and reported it
  • Investigated snap performance on RISC-V
    • Almost exactly the same performance as a static binary

Other

  • Merged icu from Debian
  • proposed-migration: reprepo vs libarchive
    • Have some ideas to fix but need queues to settle down
  • Candidate interviews

  • python3-defaults with Python 3.11 as default migrated :tada:
  • Merged a migration hint for datefudge for @adrien
  • Added finalcif, igraph, numcodecs, rust-png and cloudkitty to big_packages
    • Also mailman3 on ppc64el for @ogayot, but that is still failing
  • Investigated whether sync of python3-defaults with Python 3.11 only could be safely migrated without re-running all of the autopkgtests it triggered. @vorlon added a skiptest hint and removed the pending tests from the queue
  • proposed migration: setuptools vs numpy / ros-bloom / jenkins-job-builder
    • numpy just needed a retry with the newly migrated version
    • a regression in pandas appeared, and it needed the same
    • ros-bloom was fixed in Debian and was auto-sync’d
    • I proposed a patch for jenkins-job-builder in Debian bug #1030261 which was included in the next upload
    • I believe everything is in place now for migration, just waiting on autopkgtests

u-boot-menu

  • LP #2006693 “Merge u-boot-menu 4.2.1 from Debian” needs sponsor

AMD GPU support on RISC-V
Due to missing llvm-pipe for riscv64 some Mesa packages are not available for Jammy.

  • Started testing in Jammy and Lunar.

debian-cd
The 5.19 kernel complains about a “soft lockup” when a Radeon is installed. Increasing the kernel watchdog threshold works around the issue.

  • Created a merge request to add a kernel command line parameter in the installer image.
  • Changes in livecd-rootfs need to be addressed next.

  • Again more time on the crypto configuration specification (last touches to be done this evening)
  • Prepared a workaround for anacron 2.3-33 disabling itself when being upgraded (if the user has upgraded to an intermediate version, it’s not possible to fix this automatically) https://bugs.launchpad.net/ubuntu/+source/anacron/+bug/2006589

Other

  • Working on ddeb-retriever to build an InRelease file (LP: #2002833) to make http://ddebs.ubuntu.com/ more reliable. I spend most time how to run it locally without building a complete ddeb archive (taking days and terabytes of storage).

  • curtin
    • MP: 436862 (LP: #2004609) - fix swap partition creation with v1 storage config
    • MP: 436927 - Fix integration tests, which were using a mix of sfdisk and sysfs to get partition state. Moving to pure sfdisk gives better results.
    • LP: #2005131 (no MP yet) - start adding support to open an existing dm_crypt
  • subiquity
    • LP: #2004659 - root cause issue with installation of packages when we are online and those packages aren’t on the ISO. Due to an unfortunate sequnce of events, subiquity can be incorrectly told that there is no default route. Plan to fix this is to treat route_change events as a notification that there is a change, and then to have subiquity go retrieve the default route state rather than relying on the info from the route_change event directly. LP has more details.
    • PR: 1551 - fix CI on Lunar. Removed unneeded wheel builds, subiquity should be fully using archive packages.
    • PR: 1555, PR: 1557 - api test cleanup
    • PR: 1556 - add some automated testing for unformatted partition creation on the v2 API, and unblock creation of those partitions
  • mini-iso-tools - start improving and de-hardcoding the JSON handling of simplestreams
  • File LP: #2006404 about python3.11 and a fatal error: longintrepr.h error that can be seen in some cases

subiquity

  • reworked and merged PR 1547 to get output of mirror testing translated in the user’s selected language.
  • opened PR 1552 to add support for multiple candidate mirrors ; with automatic selection for autoinstalls and desktop installer.
  • helped investigation on LP: #2004659 (failure to install packages that supposedly are in the pool) and discussed with @dbungert possible solutions.

distro

  • Uploaded mailman3 (thanks @tsimonq2 for sponsoring!) to fix autopkgtest regression. Sadly, another test is failing, presumable on ppc64el only.
  • investigated mpdecimal FTBFS.

  • Merged systemd 252.5-2 from Debian, preparing PR for Ubuntu upload
  • +1 Maintenance

    • zeal missing builds on several arches

    • openlibm FTBFS on armhf

      • LP 2006501

        Debian already has a fix committed, but not release for a few months now. I verified the fix works for us, and have proposed uploading the fix with a maysync version to allow the next Debian upload to autosync.

    • libvbz-hdf-plugin FTBFS

      • LP 2006390

        This FTBFS because some symbols listed in debian/libvbz-hdf-plugin0.symbols are missing from the compiled library. This .symbols file was added in the most recent upload, and from what I can tell, these specific symbols may have been added by mistake. I discussed with the Debian maintainer and they agreed it would be better to just not have a .symbols file in this case. This version has synced, and successfully built in -proposed.

    • python-structlog FTBFS

      • LP 2006634

        FTBFS due to a test that has a different outcome on python 3.11. The upstream has a larger commit for python 3.11 support, so I took the relevant change.

    • aseba missing builds

    • Investigated adding some packages to big_packages as @bdmurray requested. I will make a PR for autopkgtest configs.

    • mmc-utils FTBFS on ppc64el

      • LP 2006505

        Upstream already had a patch for this, but Debian has not released a new upstream version. I provided an Ubuntu patch cherry-picking the upstream patch, and forwarded to Debian to make them aware. Thanks to Sergio (sergiodj) for sponsoring.

    • minizinc FTBFS on ppc64el

      • LP 2006489

        This FTBFS on ppc64el due to a narrowing conversion in libboost1.74-dev. There is an upstream bug/PR to fix the issue, but it has been stale for a year now. The fix should be simple, but I didn’t think it made sense to upload a new boost1.74 at this stage in the cycle.

  • Still investigating slack space at the end of our images (rpi-imager#480)
  • Investigated state of libcamera patches; appears most (all?) patches from raspios are upstream for 0.0.4
  • Worked on libcamera support in lunar:
    • current v0.0.2 doesn’t work with the v2 or v3 Pi cameras (haven’t tested v1 or HQ yet)
    • custom build of the raspios version (customized v0.0.3; actually closer to v0.0.4) also fails
    • build of v0.0.4 from debian experimental also fails
    • appears to be an issue with IPC to the IPA proxy in all cases, but more likely something going wrong in IPA init
  • Proposed migration of sbuild (LP: #2003201): appears to be a change in zstd headers/footers. Found potential error in libzstd build but doesn’t appear to change the actual build options in the package; still digging
  • Tested backport of veusz (LP: #1982839); lunar version works on kinetic and jammy
  • 22.04.2 release meeting
