Netplan

  • Added new NM cloned-macaddress “stable-ssid” option to Netplan. It fixes a crash when this option is enabled through Network Manager LP#2084234 PR#524
  • Released Netplan v1.1.1
  • Investigated a problem that happened on Jammy with the new netplan.io 0.107.1 that was backported. Cloud-init will automatically use the new python3-netplan package to parse and emit Netplan configuration. Juju will try to read the YAML emitted by cloud-init and fail due to some properties it can’t parse. We moved netplan.io 0.107.1 back to -proposed while we look for a fix LP#2084444
  • Investigated a problem with wait-online and VRFs. wait-online will block on VRFs that don’t have IP addresses (or are not optional). We need to investigate if VRF should be handled differently (wait for “carrier” only for example) LP#2084684
  • Created a task to investigate and add support for 6GHz wireless after checking a Network manager related LP bug LP#2084731
  • Bug triaging

  • Also bootstrapped .NET 9 s390x and ppc64el on Jammy and Noble through the backports PPA
  • Released preview of the new .NET snap to the snap store.
  • Enabled arm64 on the new .NET snap (see canonical/dotnet-snap#17).

This report covers the past two weeks, due to the Oracular release sprint making me skip last week’s update.

Error tracker

  • Built a script to clean up data based on a time range. Cassandra is growing too big.
    • Cleaned 2012 data two weeks ago, saved about 1% of the storage.
    • Cleaned 2013 data this week, we’ll see how much it weighted.

autopkgtest-cloud

  • Some grooming of old-ish MPs with @paride.

auto-upgrade-testing

  • Investigated an issue in upgrade testing, was due to a cowboy to fix noble->oracular. We really have to find a more reliable way to create our base images to upgrade from.

SRU phasing

Oracular Oriole

  • Participated in the release sprint, helping in progressing through the release checklist, coordinating with the flavors, and testing ISO.
  • Opened and exchanged on two bugs for my Thinkpad x201.
  • Opened an MP regarding modernizing the announcements of DistUpgrader.
  • Reported my expenses.

apt

  • APT contents generation tests with valgrind, and then fighting with gcc generating invalid reads:
    • Vectorization of a sum of unsigned char[512] resulted in 520 or 528 byte reads, failing valgrind used in apt CI
    • Optimization of strcmp(e->d_name, “partial”) to an 8-byte single instruction comparison caused another valgrind failure.
  • Also fighting with PPAs and autopkgtest and infrastructure issues all week, trying to run the tests in the testing PPA.
  • Small discourse post What's new in APT in Ubuntu 24.10?

grub

  • discussion about versioned grub packages with @mkukri

This covers the last week-and-a-half due to my attending of the release sprint and subsequent swap days I took.

Oracular Oriole

  • Did heaps of ISO testing, helped with the release checklist, learned as much as I can for next time.
  • Had my adjective chosen for the next release :slight_smile:
  • Made a small MP to the release-tools repository to ensure generated JIRA cards always use latest template.
  • Another MP to qa-jenkins-jobs to fix some broken ISO download jobs which were holding up image promotion.
  • One more MP to autopkgtest-cloud to add the ability to specify the requester of jobs when generating run-autopkgtest commands for better bookkeeping.
  • Final MP to address an issue which cropped up after release day regarding distro-info not providing a devel release when passed the --devel flag in the limbo between release and archive opening.

autopkgtest

  • Made an MP to add a dependency for required directories, handling permissions checking and creating the directory if it doesn’t exist.

server-jenkins-jobs

  • Made an MP which centralizes all arch parameters across all jobs and temporarily disabled ppc64el jobs pending migration of our single ppc64el worker.

git-ubuntu

  • Enabled a new Jenkins job for git-ubuntu which launches LP builds of the snap for non-amd64 architectures.
  • In the process merged in an MP flagging the relevant script in the git-ubuntu repository as executable.
