subiquity

  • Coordinating with desktop to fix an issue when running manual partitioning and then switching back to guided partitioning. The installer on noble would not “forget” actions done during manual partitioning.
  • Filed bug 2059389. The installer was sometimes suggesting to resize the partition of the installation media that is used to store installation logs. Merged PR 1957 to address the issue.
  • Triaged some bug reports and experimenting with automation.
  • Helping with MOK enrollment.

openjdk/Java

  • CRaC prototype - hacked up an openjdk-22 package with the openjdk/crac upstream and the CRaC’ized criu as a build dependency, ran sanity test (OK)

  • FIPS provider prototype - more refactoring, wrote the main Provider class. Provider tests pending.

  • TCK - tested the Python runner script, cleaned up repositories (no links because this contains licensed material).

  • openjdk-lts armhf FTBFS - prepared patch, but waiting for re-boostrapping of openjdk-lts being done by vpa1977

Shorter week due to the holiday weekend.

Subiquity

  • Continued work on my spec for MOK enrollment, with some additional help from @ogayot (thanks!)
  • (draft) PR #1959 - Adds some (debug) logic to Subiquity for faking ubuntu-drivers into installing drivers in a VM. This will be helpful for testing (and developing) MOK enrollment since we don’t have access to relevant physical hardware.

Distro

+1 Maintenance this week. Nothing in particular to report here, I have been helping with the general archive analysis and rebuild efforts due to the xz-utils incident.

General

  • sick: was out hard Sunday/Monday, dragging a bit yesterday, hopefully back
    to full throttle today

Distro

  • dealing with CVE-2024-3094!
    • deleted all amd64 binaries from the release pocket built later than Feb 25, when the trojaned xz-utils landed in noble-proposed
    • copied back pre-Feb 25 versions of all affected packages to noble-updates, to have a baseline for rebuilds on amd64
    • done this way to avoid having to rebootstrap on armhf, since the t64 renames landed in this window
    • no-change rebuilds uploaded to -proposed for all affected packages
    • been managing the migration of those rebuilds ever since

Release

  • aiming to get all dependencies migrated today so that we can start image builds for 24.04 beta
  • as of this morning, livecd-rootfs is not installable and debootstrap is not possible, so this is a big lift
