dotnet

  • Attended the weekly .NET partners sync meeting.
  • Added GitHub Workflow reporting to the mount tests in the dotnet-content-snaps repository (canonical/dotnet-content-snaps#14).
  • Fixed dotnet8 autopkgtest failures in oracular by bumping the memory limit of the cgroup-limit test (canonical/dotnet-regular-tests#14).
    • Reported the issue in a Launchpad bug (LP: #2077334).
    • Fix has been uploaded, package migrated, and autopkgtest issues are now fixed.
  • .NET 8 ppc64el on Noble made it to -proposed but the bootstrap PPA still needs some tweaking for the ppc64el package to build.
  • Implemented support for external Git repositories on a debian source-tree in Flamenco (pending review, canonical/flamenco#5)
  • Implemented the .NET installer support for standalone .NET content snaps, which means that installing .NET content snaps that depend on components from other .NET content snaps will no longer also install these other snaps, since they now also ship these dependencies and their respective mount units.

  • proposed-migration
    • man-db vs firejail - already fixed by the time I had a look
    • gzip stuck in “candidate” - was making zutils/botch uninstallable, zutils needed a sync then botch needed an armhf retest click
  • still working on livecd-rootfs and kernel things - kernel changes for minimal layer probably done, more testing required
  • spec updates and made decisions related to handling of 6.8/6.11 kernels
  • debugging of CLA bot problems on Add TPM-backed encryption instructions by GlitchWitch · Pull Request #2059 · canonical/subiquity · GitHub - the github username check is case sensitive, so people who have signed the CLA may yet fail the check if there is a difference in how they setup their github username versus how they signed the CLA
  • greenhouse - 2 interviews and a THT, prep for another interview that needed a new set of questions

Go

  • Prepare golang-1.22 backport to focal (LP: #2076069). Thanks @vpa19771 for sponsoring.
  • Investigating golang-1.22 FTBFS in bionic and xenial on arm64. (LP: #2077608)
  • Continue fixing the remaining packages that FTBFS with golang-1.23 and the proposed migration.
    • libpod FTBFS (LP: #2077610, Merge proposal)
    • Retry multiple packages’ tests that were uploaded last week. Now most packages don’t show autopkgtest regression. But they are still not migrated. So working with @ginggs to figure out the reasons.
    • golang-opentelemetry-otel only fails on autopkgtest.ubuntu.com infra. Still trying to reproduce that locally.
    • Move golang-github-hillu-go-yara/ppc64el test to big_packages.

Distro

  • Working on backporting nbd autopkgtest to noble (LP: #2077415)

  • Asked access for the team to the environment behind merges.ubuntu.com in RT #165934.
  • Quickly cowboyed a robots.txt to try to lower the amount of bot requests, and blackholed a few too.

Fairly short week due to bank holidays.

  • glibc: a story of migration
    • verified the Noble SRU so that Lukasz could accept it into -updates
    • Looked into the remaining regressions against glibc 2.40 in oracular
      • systemd regression is not a glibc problem but just a testsuite issue
      • gap-guava was more difficult, finally tracked it down to an uninitialized array spewing garbage from the remnants of previous stack frames. Gotta love C.
    • A few NCRs for some packages with hard version deps on glibc
    • Made zlib migrate out of -proposed as it was blocking glibc due to the s390x 32-bit binary removals (thanks @frank for fixing the build)
  • Some Greenhousery
  • Fun with crypto algorithms.
