Hello everybody,

It’s time for a weekly update from Foundations :sparkles:

Courtesy ping:

Please, post your updates. Thanks!

I am doing a test rebuild of OpenSSL 3.6 in a PPA Bug #2138634 “Test rebuild OpenSSL 3.6” : Bugs : openssl package : Ubuntu
The builds are almost finished, I should have a report soon https://launchpad.net/~ravi-sharma/+archive/ubuntu/test-lp2138634/+packages

I have 2 MPs for Distro cryptography pending review

I spend some time last week looking at Patch Pilot organisation. It seems the Sponsoring Queue is moving again. :blush:

TPM/FDE

  • Patched Plymouth to show password toggle hint (LP: #2138715)

Distro work

Plucky EoL

  • Cleaning a few things (command-not-found, error tracker, etc…)
  • Updated meta-release.

Noble .4

error tracker

  • Uploaded and verified django-tastypie to Noble and Questing: https://bugs.launchpad.net/ubuntu/+source/django-tastypie/+bug/2136109
  • Finished validating Copilot’s work. Commit history contains a lot of details about how Copilot is behaving. I’m now teaching Copilot how to write some tests, with mixed success: it’s fine for the boilerplate, but most tests actually don’t really test things, and could let many kinds of breakage through. Also it’s pretty bad at expanding the current test dataset.

I spent a lot of the week investigating and helping with the cgroups vs systemd vs resolute issue that was preventing all resolute livefs builds from succeeding. These builds are now going again, finally.

This being fixed means I was able to successfully build an amd64v3 cloud image on Launchpad for the first time, yay!

It might be nice to offer the community updates to the issues with amd64v3 packaging since you had encouraged testing.
