Partial week due to public holidays.

glibc:

  • Prepared SRUs for Jammy and Focal, including a bit of bug grooming.
  • In the middle of rebasing 3 years worth of Ubuntu-specific changes on top of Debian’s packaging. Fun times!

+1 maintenance

I looked at packages that are FTBFS and stuck in proposed migration due to missing build.

  1. gitlab-ci-multi-runner

    The package has long history of ftbfs both in Ubuntu and Debian.

    Request removal https://launchpad.net/bugs/2021461

  2. delve

    bpftool needs to match running kernel version. Not possible to have a
    working bpftool command in Ubuntu build environment. (Disclaim: I made the requirement for bpftool in Debian. it works in Debian because the bpftool is packaged differently. I would revert that change in Debian if no solution found when Debian is not in freeze.)

    https://launchpad.net/bugs/2021481

  3. librnd + camv-rnd + pcb-rnd

    camv-rnd and pcb-rnd are in dep-wait status, it needs librnd > 4.
    It’s a small library transition. So I just ask @ginggs to kick off the transition.

    Also ask for revoking the blacklist for sch-rnd since it has stable release now.
    https://launchpad.net/bugs/2007172

  4. perl related

    Several packages FTBFS with same test failure:

    event webhook_request of session KGB for DIR handler ‘^/webhook/’. As
    reported by Kernel: ‘No such file or directory’, perhaps the session name is
    spelled incorrectly for this handler? at /usr/share/perl5/POE/Session.pm
    line 483.

    I’m still debugging that.

  5. godot

    FTBFS in Debian too https://bugs.debian.org/1031132
    Imported the bug to launchpad and add a update-excuse bug for reference.

  6. libs3

    FTBFS on ppc64el only. Caused by -Werror=stringop-overread. Looks like the
    difference is -O3 vs -O2 build flags between Ubuntu and Debian.

    Patch attached at https://launchpad.net/bugs/2021564

  7. libtgowt

    FTBFS on riscv64, but previous version not. The new version needs upstream
    explicit support in its build config. However this library is only for
    building telegram-desktop.

    Request removal https://launchpad.net/bugs/2021567

  8. kickpass

    FTBFS on amd64 due to LTO. Caused by a pie patch which is added by the Debian
    maintainer (Can be safely dropped).

    Patch attached at https://launchpad.net/bugs/2021577 and forwarded to
    https://salsa.debian.org/debian/kickpass/-/merge_requests/1

  9. pushpin

    FTBFS on ppc64el, riscv64, s390x. Same on Debian, and Debian has removed the packages on these architectures.
    Request removal https://launchpad.net/bugs/2021594

autopkgtest

  • Resolved an issue with updating the autopkgtest-cloud-worker charm in staging by updating the charm to pin the version of pyaml and submitted an MP with that change. This also involved wrestling with juju a wee bit.
  • With @paride resolved another issue updating the autopkgtest-cloud-worker charm in staging this time by pinning PyYAML. See the MP for some more details.
  • Updated the autopkgtest-cloud-worker charm in staging and production to revision 156 which includes fixes for a bug regarding images potentially having packages from -proposed in them and a bug regarding a trailing dot in FQDN of hosts in PS5.
  • Submitted, merged an MP which documents the process for updating the autopkgtest and autodep8 code in the autopkgtest environment.
  • Submitted an MP updating the mojo/service-bundle by removing the autopkgtest-cloud-worker-lrg units and moving test runners to the autopkgtest-cloud-worker units.
  • Removed autopkgtest-cloud-worker-lrg units from production as they had been replaced by autopkgtest-cloud-worker units and were no longer being used.
  • Pinged IS regarding restarting neutron on s0lp4 in scalingstack-bo02 as the s390x queues were slowly processing again. See RT 155441 for details.
  • Submitted a request to have a staging proposed-migration setup in PS5 on the ubuntu-qa bastion. Also reported a bug about the form.

Ubuntu

  • Retried autopkgtests which had failed for stable releases using retry-autopkgtest-regressions.

Misc

  • Scheduling / coordinating team holidays.
  • Reviewing candidate applications.
  • Reviewed and closed some outstanding RTs that were no longer valid.

openjdk-lts:
