  • ISO image testing
  • Found fractional scaling selection can be broken in “interesting” ways (LP: #1993174)
  • More ISO image testing
  • Found incorrect audio output selection on Pi 400 (LP: #1993316)
  • … and Pi 4 (LP: #1993347)
  • Tested console audio fix in -proposed (LP: #1991254)
  • Re-tested the official DSI display under -proposed kernel 5.19: KMS works! Ish. Touchscreen doesn’t work, and neither does rotation, but at least there’s graphics! FKMS still working fine (LP: #1970603)
  • ISO image re-testing
  • Fixed incorrect FK_FORCE reference in flash_kernel_set_root (LP: #1955353)
  • Lots of blog post writing / updating / publishing (on GPIO, Hyperpixel, and MicroPython (tbc))
  • Firefox meeting
  • Bug triage
  • Did I mention the ISO image testing?

subqiuity

  • imported autoinstall documentation from discourse to the subiquity tree. Added a build step to simplify the export operation to discourse.
  • updated the autoinstall reference document to include new keys that were added post 20.04.
  • helped with the flash-kernel issue.
  • fixed UI crash upon reaching the custom storage screen while a storage probe operation is ongoing (race condition). The issue was observed by Frank multiple times on s390x hardware.
  • worked around an overlay unmount issue after listing third-party drivers. The umount command failed on riscv64 with EBUSY (other architectures might be affected). The root cause was not identified but the overlay unmount failure for third-party drivers has been made non-fatal.
  • tested a few Subiquity installs on kinetic (including proxy-only HTTP).
  • reported DNS configuration inconsistency in Subiquity installs. Marked low priority.

misc

  • going slowly through the steps to apply to ubuntu-bug-control

Release Team

Happy Release Week!

Archive

  • finalizing kinetic archive for release.
  • zeroed NBS! Thanks, Simon!
  • zeroing priority-mismatches, which should apparently be started earlier in the cycle because it left us with two packages we had to promote but didn’t want to (libfdisk1 for systemd; sgml-base for `libidn2’)
  • Uploaded three packages that depend on aircrack-ng to make them also build-depend on them, so that no uninstallable binaries are being generated on s390x, making https://people.canonical.com/~ubuntu-archive/proposed-migration/kinetic_uninst.txt a bit cleaner for release
  • late NEW processing of a couple of universe syncs
  • one of these cleared a sync-blacklist extra-removals dependency, so synced back another package
  • took care of remaining removal requests

General

  • spec reviews for impending roadmap sprint

systemd

  • Road map planning for next cycle
  • Helping to investigate a bug at the request of server team

Other

I got annoyed by typing too much when diffing source package. I wrote savedebdiff to save some time: https://github.com/bdrung/bdrung-scripts#savedebdiff. You might find that useful as well.
