Distro

• came up and shared a better work-around for m2crypto with openssl 3.4; it was then uploaded to Debian: https://tracker.debian.org/news/1603082/accepted-m2crypto-0420-21-source-into-unstable/*
• fixed FTBFS/test failure in freezegun with python 3.13 and posted debdiff on the Debian bug for the FTBFS: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1092458#15 (I can tailor it to Ubuntu too but favored a fix in Debian due to the current depth of test queues in Ubuntu); looking for a sponsor too!
• Experimented pulling patches from liboqs’ upstreams inside liboqs directly to ease make maintenance of d/copyright viable, worked well. This will either need a dfsg source repack or expanding coverage (would be better)
• @tsimonq2 uploaded https://launchpad.net/ubuntu/+source/gnupg2/2.4.4-2ubuntu22 which drops the build of gpgv-win32.exe which is only used by debian-installer

Misc

• Drafting a plan for post-quantum cryptography support in Ubuntu over the next few years
• Preparing a few crypto-config updates before
• Experiments with ways to run an application under a specific crypto-config profile (there are two main approaches but each comes with its drawbacks)

[pushkarnk]

Plucky

• Uploaded “cleaner” flash-kernel merge (LP: #2081313)

Oracular

• Verification of rpi-eeprom update to support CM5 flashing (LP: #2085903)

Distro

• initramfs-tools: I finished this huge merge. There were 248 commits and 35 Ubuntu uploads since the last merge. The rebase is refactored/sqashed down to 87 commits. To make sure the merge is correct, I compared the results by a branch where I picked the commits from Debian instead. This branch contains 93 commits. I created more merge requests for Debian:
  • Explicitly call “set -e” instead of specifying on shebang
  • netinfo_to_resolv_conf: clear variables between sourcing
  • netinfo_to_resolv_conf: add net_file to local variables
  • Filter block kernel modules by symbol regex from dracut
  • Do not install ARM/RISCV specific modules on other architectures
  • hook-functions: add squashfs driver
  • hooks/resume: Fix resume device type check
  • It took some time to figure out that shellcheck SC2251 recommended the wrong solution. I reported that: The “Use && exit 1” for SC2251 can result in a wrong exit code
• tzdata: Merge 2024b-6 from Debian

proposed migration

• Released ionit 0.5.1 and 0.5.1-1 to support Python 3.13

other

• Ubuntu Governance Sync Meeting
• Grading take home tests

autopkgtest-cloud
