autopkgtest

  • Added a wheelhouse.txt file pinning pip versions thereby fixing the charmcraft pack failure with autopkgtest-cloud-worker. Added the same wheelhouse.txt file for the autopkgtest-web charm.
  • Updated, tested the autopkgtest-cloud-worker charm in staging. Then updated the charm in production.
  • Wrote, tested and added an lpcraft configuration file to the ~ubuntu-release branch of autopkgtest which runs pyflakes. This’ll get run on every MP for that branch.
  • Provisioned 2 new armhf workers replacing two downed units. Additionally, used the same_host hint to make the node creation process less painful.
  • Submitted an MP updating our documentation so that the same_host hint is documented.
  • Wrote, tested and added an lpcraft configuration file to the ~ubuntu-release branch of autodep8 which runs autopkgtest against the branch (which contains autopkgtest tests).
  • Submitted a merge proposal which improves on the above by using autopkgtest from the ~ubuntu-release branch of autopkgtest in addition to the packaged version for Focal.
  • Updated, tesed the autopkgtest-web charm in staging. Then updated the charm in production.
  • Reviewed, merged an MP from Simon Quigley updating the ubuntu-release branch of autodep8. Then updated the version of autodep8 in staging and production.

Error Tracker

  • Removed crash reports from the Error Tracker for a user.

Ubuntu

  • Added r-cran-prophet, seqan3, psychopy, rust-ahash, golang-github-aws-aws-sdk-go-v2, pycuda, pandas, bmtk, praat to big_packages.
  • Uploaded lsb-release-minimal with some test ordering changes as having busybox as the shell broke log file grabbing see bug 2004500 for more details.

Misc

  • Roadmap sprint week.
  • Administrative (travel) work.

Archive

  • sourceful NEW processing, got the queue down to zero
  • processed various removal requests, working towards unblock of python3-defaults
  • process-removals from Debian; almost ready to remove python2 from lunar, waiting on the kernel packages’ test suite to be updated to python3

+1 Maintenance

  • pushing on the python3-defaults transition. Getting closer, but britney now telling us about blockers that it should’ve told us about before (plplot → gnat → libgnatcoll-bindings)

General

Roadmap mid-cycle; lots of good discussions :slight_smile:

ubuntu-image

  • Made some updates and merged PR to clean up /run
  • Made some updates and merged PR to clean up base tarballs
  • Began work on spec to support revision assertions in ubuntu-image core builds
  • Investigated “bug” for Field Engineering team. This turned out to be an intentional design decision from snapd

Miscellaneous

  • Finishing up +1 maintenance, see ubuntu-devel mailing list for more details
  • Candidate interviews
  • Take home test reviews

    • Truly a weird issue. It gets a broken pipe on s390x only, but consistently. I’ve tried a few different sets of triggers but had no luck.

Distro

  • Investigated a new autopkgtest failure that showed up in libcap2 that happens only on armhf that seems to be related to the test environment. We are considering disabling that test on armhf for now as it’s not reproducible in Lunar.

  • Addressed some issues found in the MIRs I’ve submitted recently

Netplan

  • Finished implementing the first batch of autopkgtests for the NetworkManager+Netplan integration
  • Added a new step to our Github CI to check for runtime memory issues in the Netplan C code (PR#321)

  • Attending multiple meetings from the mid-cycle sprint

apt

  • Responded to review of spec for Ubuntu flavour of raspi-config (need to respond to second round of comments)
  • Investigated Firefox acceleration on Pi (requires mesa currently in jammy, and for base of snap to move to Core 22; current issues with building Firefox on Core 22)
  • Proposed migration of python-hypothesis: pybuild-autopkgtest wasn’t finding the python3-exceptiongroup build-dep (despite it being explicitly listed in d/control, as opposed to the python-version limited requirement in setup.py); possibly related to LP: #2002819 (thanks @schopin for noting that!) or they may be some other issue (still digging into the tooling). Fixed by @tsimonq2 in the meantime, by-passing the autodep8 tests
  • Verified SRU of linux-firmware-raspi (LP: #1989713)
  • Uploaded new version of raspi-config for lunar
  • Uploaded new version of rpi-eeprom for lunar (LP: #2004569); this may become an SRU in future
  • Investigated slack space at the end of our images (rpi-imager#480); there’s only about 200MB slack at the end (in line with fudge-factor in livecd-rootfs), but the rootfs is only 66% full (1.2GB free!)? Need to dig further…
