Netplan

  • Relaxed Netplan validation for tunnels. Netplan enforces that both “remote” and “local” IP parameters are used for tunnels. The parameter “local” is not really required. It was affecting Netplan-everywhere. When a tunnel was created without the “local” parameter the connection creation would fail (PR#407)

  • Working on a fix for netplan apply when the loopback interface is managed through Netplan. apply is taking the interface down but NM is not bringing it back (PR#408)

  • Continued the investigation of an issue related to the Netplan’s generator. It’s causing a race condition due to the fact we are calling udevadm from the systemd generator. Also created a PoC to replace the generator with a regular system service. More details here, here and here.

  • fixed crash when a network interface (i.e., Wi-Fi or ethernet) disappears before or during the install. PR 1789

  • fixed Wi-Fi interface not listed in dry-run mode. PR 1785

+1 week

Remaining bits from the +1 week:

  • jdupes: Fails to build on i386, because it introduces a new dependency: libjodycode. I asked on #ubuntu-release to add libjodycode to the list of packages that we build on i386.
  • stegseek: 0.6+git20210910.ff677b9-1 fails to build, because libjpeg62-turbo-dev is not available on Ubuntu. I changed the build dependency to libjpeg-turbo8-dev and uploaded 0.6+git20210910.ff677b9-1ubuntu1 to Ubuntu.
  • pytrainer: 2.2.1-1 has a broken dependency on python2, because dh-python replaced the shebang /usr/bin/env python by /usr/bin/python2. Enforce /usr/bin/python3 as shebang, uploaded that as 2.2.1-2 to Debian unstable, and synced to Ubuntu.
  • zict: zict 3.0.0-2 test_stress_different_keys_threadsafe hangs on ppc64el (LP #2033759). This behavior can be reproduces by running the test suite only on one core (on ppc64el and amd64). So I reported it upstream: https://github.com/dask/zict/issues/107
  • pytorch-vision: FTBFS with ffmpeg 6.0. Opened LP #2033761 for it and linked the Debian bug.
  • python-gsd: 3.0.1-3 was not built on s390x. This was an intentional change in the Debian package, because upstream does not support big-endian systems. So I asked the archive admins to remove the python-gsd s390x build from mantic: https://bugs.launchpad.net/ubuntu/+source/python-gsd/+bug/2033780
  • python-libnacl: 2.1.0-1 failed to build due to a recent poetry-core breaks poetry. Since poetry 1.5.1+dfsg-4ubuntu1 is now in mantic, I retried the build successfully.
  • python-socks: The autopkgtest fails for 2.3.0-1, because it needs the tiny_proxy module (LP: #2033899). So I packaged that module as part of the Debian Python Team. python-tiny-proxy got accepted a few days later and I opened a FFe sync request (LP: #2034120) and uploaded python-socks 2.3.0-2 to unstable and synced to Ubuntu.

Distro

  • dcfldd: Doing more debugging on the test failure and nailing it down to -O3 on ppc64el (excluding lto and amd64) (LP: #2033405)
  • isc-dhcp: Uploading 4.4.3-P1-2ubuntu5 to remove initramfs-tools integration from isc-dhcp-client (LP: #2024164) and fix the autopkgtest.

  • subiquity
    • support the work to merge the canary and desktop isos into a single ISO
      • PR: #1783 - test and merge apt-related Subiquity changes
      • PR: #1781 (LP: #2028889) - min size recommendations update - fix different recommendations between TPMFDE and classic offerings when they aren’t actually all that different
      • all the testing and livecd-rootfs reviews
    • PR: #1787 (LP: #2034270) - fix CI breakage related to a disk of size 1MiB
    • investigation on getting info from rsync useful for a progress bar. I have a proof of concept. --info=progress2 is part of it, but it’s not that simple due to the %complete jumping around.
    • document the translations process and start doing so
    • no pr yet (LP: #2026225) - have a working build of livecd-rootfs changes needed to allow installing arbitrary kernels for the desktop iso. Required for OEM and if someone opts into a specific kernel. Ready for branch rebase + MP.
    • LP: #1961079 - rebase branch and rebuild test snap for customer, it aged out
  • investigate LP: #2034606 - failures to install with multipath, also were blocking Subiquity CI. This turned out to be an unfortunate packaging bug where the initramfs scripts weren’t executable on multipath-tools. Root cause found by mwhudson, he uploaded, fix confirmed.

I did a whole bunch of grub2 uploads in Debian to fix regressions reported in unstable, some more grub2 regression fixes, and helped @mkukri get started.

I had planned to work on software-properties deb822 support some more but ultimately did not get around to it much.

this was/is my first week at canonical, and as a foundations team member.

i’ve spent most of my time so far learning about the packaging process, and the various tools that go along with it.
