  • subiquity
    • PR: 1320 - fix a unit test that was dependent on the actual list of user groups in the running environment
    • PR: 1323 - finish up work on a ‘use_gap’ autoinstall directive that allows for installing into an existing gap when doing guided partitioning, similar to d-i ‘biggest_free’.
    • Did a set of 20 VM tests as part of use_gap, found some interesting bugs.
    • PR: 1326 - fix issue on BIOS when using ‘use_gap’ and there is a small disk present. Can happen when using cloud-localds to seed the autoinstall.
    • PR: 1327 - improve the allocated number assigned to partitions. When mixing preserved and non-preserved partitions, it was possible that there would be a number overlap. Will need further work for msdos partition tables.
    • PR: 1328 - improve guided unit tests to cover LVM
    • PR: 1329 - fix a bug in handling of the location of the autoinstall file.
    • PR: 1332 - logging to help debug of recent guided mode work
    • PR: 1333 - merge below probert change
    • Specification work
    • Review PR: 1321, 1322, 1324, 1325, 1330, 1331
  • probert
    • PR: 119 - bring over fix from PR: 117 to the stable branch

  • VisionFive

    • SRU flash-kernel: @waveform sponsored

    • kernel packages tests

  • Nezha:

    • Fix nezha-boot0 and re-uploaded by @slyon
    • kernel packages tests

  • livecd-rootfs:

    • Fix Nezha and VisionFive since I had a real kernel package, PR updated
    • Built images for both boards successfully

  • MIR usb-creator:

    • Fix libisoburn testsuite: uploaded by @vorlon
    • Add symbols file to libburn, libisoburn, libisofs
      → MIRs requested TODOs should be ok!

  • MOTU application preparation :slight_smile:

systemd

  • systemd-oomd
    • Opened upstream PR to honor ManagedOOMPreference for all cgroups: https://github.com/systemd/systemd/pull/23764
    • Tested these patches out in Jammy, and got a feel for the integration worked required
    • Met with @slyon and @vorlon to give updates on systemd-oomd and discuss next steps
    • Have been running ManagedOOMSwap=auto on -.slice on my machine to test the (likely) SRU fix for systemd-oomd on Jammy, and had a script monitor my mem and swap usage and log when the SwapUsedLimit threshold was reached
    • I will send out a message on ubuntu-devel with updates later today
  • Opened v251 merge PR for @slyon to do some early review: https://code.launchpad.net/~enr0n/ubuntu/+source/systemd/+git/systemd/+merge/425171
  • Worked on autopkgtest for v251
    • I think I have a fix for flaky upstream-1 and upstream-2 tests
  • Opened upstream issue about linker warnings building on ARM: https://github.com/systemd/systemd/issues/23789
  • Opened LP 1979215 for gnu-efi (causes systemd FTBFS), which is another regression caused by linker warnings added in recent binutils

General

  • Another short week - was off most of last week (+ a bit of a cat emergency on Tuesday)
  • SRU reviews and releases
  • NEW reviews
  • Some FDE discussions
  • Backlog review with the team
  • Preparation tasks for 22.04.1
  • Created first kinetic language-packs. Had some issues getting those done due to issues after the instance move. But now working and enabled building weekly

  • Discussions regarding some NetworkManager <-> netplan desktop integration, prepared Jira card for some investigation work

ubuntu-cdimage and images

  • Fixed multiple failing unit tests - some of which were related to our simplestreams support
  • Investigated possible issues with generation of simplestreams for release trees. Will keep an eye out for issues there in the future, as I still suspect some race conditions
  • Created new test desktop images for Intel IOTG. Still working on the server images, making sure that the right kernel is pulled in
  • Copied some Xilinx images for Alex
  • Reviewed Michael’s netboot ubuntu-cdimage changes - merged those but followed up with some unit-test fixes (as we now had a relatively ‘good’ unit testing story).

Ubuntu Core

  • Added core22 to automated promotion
  • Investigated issues with auto-promotion failing due to Trello API changes. pytrello wasn’t really updated, so worked-around that by using a fixed pytrello locally.
  • Ubuntu Core 22 released last week \o/

Ubuntu Image

  • Added some comments on the germinate step of the new-world ubuntu-image classic build PR. Looked at the code but will be re-looking at it shortly again.
  • Reviewed PR from William for fixing the snap/seed manifest formatting

Apport

Fixed several bugs in apport:

  • attach_journal_errors is causing a ValueError crash (LP: #1978487)
  • Broken contact URL in German translation (LP: #1978301)
  • /usr/share/apport/apport:AttributeError:/usr/share/apport/apport@531:parse_arguments:print_usage:_print_message (LP: #1979211)
  • apport_python_hook: FileNotFoundError if cwd was deleted (LP: #1979637)
  • apport_python_hook: Crashes if os.getcwd() throws FileNotFoundError (LP: #1977954)

I will prepare a new upstream release soon (which will be uploaded to kinetic). Then I will prepare the SRUs (with all those fixes).
