  • armhf time_t work: fixed analysis on 10 packages (although a-c-c runs out of address space on libclang-15-dev), made improvements to the driver script to parallelize work and reduce overhead
  • discussions about which version of openssl to package next (we’ll most likely stick to 3.0 due it being LTS)

  • Review of @andersson123’s MP for updating ubuntu.csv on all the machines when opening the archive for a new release.
  • Rebooted the existing autopkgtest-cloud-worker with a zfs compressed /tmp parition (after switching it to use teh ceph volume) and rebalanced the worker services so that we still have the same number of services running but spread across four workers now.
  • Submitted, merged an MP which better clarifies what seed-new-release (part of the arhive opening process for autopkgtest) does.
  • Documented the process for bringing down an autopkgtest-cloud-worker gracefully.
  • Investigation into the hanging network-manager test cases on amd64. It seems to be an issue with the instances not being reachable after running a specific test.
  • Updated the autodep8 code branch on all the test worker units so that a code change is available. Found out the code update wasn’t enough and had to run a make install on the workers.
  • Reviwed @andersson123’s MP delinting the autopkgtest-cloud code.
  • Submitted an MP adding Canonical Ubuntu QA as a point of contact about never run packages.
  • Submitted an MP switching the flavor used in create-nova-image-new-release to autopkgtest.


  • Add ubuntu-release-upgrader/i386/* to never_run as its deps are unavailable.
  • Submitted an MP documenting the process for updating the ubuntu-release.kpi.u.c site when opening a new release. Merged it after review by @seb128.


  • Conducted an interview.
  • Spec review of Foundations team bug sync’ing to JIRA.
  • Administrative work

+1 week

Remaining part of my +1 shift last week:

  • golang-github-tdewolff-parse: Autopkgtest for golang-github-tdewolff-minify 2.12.4-1 on amd64 fails. golang-github-tdewolff-minify 2.12.4-2 fixed the failure with the new golang-github-tdewolff-parse version. I retried the test with specifying the new version.
  • stress-ng: bug report #2019079 already described the pthread test case failure on armhf and pointed to an upstream commit that fixes it. I tested the fix in a PPA and uploaded 0.15.07-1ubuntu1. Then I noticed that I falsely assuming that the armhf test in my PPA succeeded. The pthread test case did not crash any more, but did not exit any more and it ran into the autopkgtest timeout. I found another stress-pthread upstream commit that fixes a endian issue. Adding this second patch made the autopkgtest succeed. I uploaded 0.15.07-1ubuntu2, reported the success uptream on and submitted the changes to Debian.

    I try to split the logic commits with git-ubuntu. But they are many old changes. So I’m still verifying the commits are split correctly. WIP:

I’m on +1 this week.

Oddly enough, I seemed to have picked time-consuming issues to work on this week, which makes for a short status:


Picked it up from last week’s shift. I banged my head against it for a day and a half with a little bit of progress, but no solve in sight, see


This was more productive. Synced from Debian, then dropped because it was holding up the python3.11 transition, then re-synced, the autopkgtests fail in Ubuntu but pass in Debian.

It turns out to have been caused by our pkgbinarymangler PNG optimization pass that changed the color encoding of the icons, triggering a latent bug in the tk backend. There was an upstream fix for it.



Retried in bulk the failing tests, both against dh-cargo and migration-reference. Given the nature of the changes, it’s unlikely to have caused regressions in those packages.


Ongoing. Human error on the Debian side, the new upstream version was uploaded to Debian unstable and then synced. That triggered quite a few autopkgtest regressions due to a change upstream to disallow calling native symbols (???).

  • Merged openssh from Debian unstable
    • Fixed LP 2017434 “README.Debian.gz instructions for disabling socket activation inaccurate”
  • Working on LP 2020474 “openssh-server-1:9.2p1-2ubuntu1 cannot be installed from active ssh session”
    • This is caused by upgrading from a version of openssh-server that contains the patch from LP 2011458, therefore only mantic is affected.
    • I believe I have fixed the root cause, and I am working on packaging changes to make the upgrade path smooth.
  • Reviewed for Julian
  • Merged avahi from Debian unstable (LP 2020383)
  • Working on a batch of armhf header compilation failures
