  • Integrated the PSPester test suite to the PowerShell CI leg. Still investigating test failures and whether it’s worth it to keep the ‘test’ step active given the inability to set tests as “superficial”.

    • Desktop images now launch gnome-initial-setup (instead of ubiquity)

Distro / +1 maintenance

  • Investigated FTBFS for a cluster of 9 Python packages related to documentation generation. Built them in a this ppa. Migrating 8 packages would need accepting a package from the NEW queue (mkdocs-get-deps) and breaking two build-dependency cycles (mkdocstring-python-handler vs. mkdocstrings and python_mkdocs vs. mkdocstrings).
  • Other FTBFS fixed:
    1. linuxcnc
    2. uvtool

Misc

  • Code reviews, specification review
  • localsearch MIR review with help from slyon

Distro

  • Prepare strace 6.14
    • Kernel 6.14 has been released and a few hours later, strace 6.14 has been released
    • not uploaded due to beta freeze but ready
  • Investigated failures in the test rebuilt
  • libengine-gost-openssl:
    • fails due to perl tests that weren’t being run before; cmake runs two of them in parallel but both use the same filenames
    • upstream PR: https://github.com/gost-engine/engine/pull/469
    • not uploaded due to beta freeze but ready
  • libotr
  • libscrypt
  • python-cryptography:
    • build-depends on librust-asn1-0.17-dev but we only have librust-asn1-0.20-dev in the repos now
    • updating deps wasn’t easy and seemed to change a lot of them plus the build was not using system libs anyway
    • switched to vendoring deps since this is in main and per MIR doc
    • maybe ready now: proof-read, testing now
  • libnss-ldap, libpam-ldap, ldap-auth-client: asked for removal

  • tzdata: The saga continues. 2025a got released from -proposed, but the update for 2025b is in progress.

Upstream work

Several of my Debian initramfs-tools patches were reviewed. I incorportad the review feedback and then those PRs got merged. Expect a release soon.
