  • And posted a call for testing on discourse
  • And wrote a customarily lengthy blog post all about it
  • Got a few comments on the latter which I’ve responded to and am now testing to make sure my answers actually work!
• Prepped changes to the pi-gadget for the A/B boot mechanism
• Prepped changes to the Pi’s platform seed to incorporate new flash-kernel binary package for A/B booting
• Filed ubuntu-raspi-settings bug to remove mkswap.service (LP: #2116275)

Toolchains

• rustc-1.85 is now in the archive!
• The updated rust-defaults is currently in proposed, waiting on rust-sudo-rs and rust-reqwest regressions.
• The rustc-1.82 Focal backport (required by hwlib) now builds successfully on all platforms. Particular effort was put into solving RISC-V LLVM 19 build issues. I’ve bumped the version number and will send the results to Security after this final PPA build.
• rustc-1.86 work is underway. I’ve updated all existing patches such that they apply cleanly onto the new upstream source, and now I’m working on pruning Windows dependencies from vendored sources.

Documentation

• Finished bugfix and update to the Toolchains Availability page. I must wait until rust-defaults has been updated to point to rustc-1.85 before merging the changes.
• Polished up my personal documentation on Rust maintenance in anticipation of new teammates!

Miscellaneous

• Peer Buddy correspondence.

PowerShell

• Bootstrapped PowerShell on ppc64el, the last architecture missing from the bootstrapping task that enables the PowerShell snap on arm64, s390x, and ppc64el.
  • PR is currently open (in draft stage) to enable GitHub Actions builders for these three new architectures (Add support for arm64, s390x, and ppc64el snaps by mateusrodrigues · Pull Request #15 · canonical/powershell-snaps · GitHub).
• Investigating PowerShell Preview build failure on .NET 10 Preview 5 to include the fix in the PR above before marking it ready for review.

[vpa19771]

craft-parts:

• raise feat: add parallel parameter to autotools plugin by vpa1977 · Pull Request #1167 · canonical/craft-parts · GitHub to allow building openjdk with autotools plugin

openjdk:

• investigating https://bugs.launchpad.net/ubuntu/+source/openjdk-21/+bug/2095441 - have a reproducer and offending commit
• prepared early access uploads before security release

kotlinx:

• working on kotlinx-coroutines packaging

[hyask]

open-iscsi

• Merged from Debian: https://code.launchpad.net/~hyask/ubuntu/+source/open-iscsi/+git/open-iscsi/+merge/488607

rails transition

• Helped with a few autopkgtests with correct triggers added. Here is the Matrix thread with some details.
• Fixed ruby-omniauth-rails-csrf-protection autopkgtest in Debian: https://lists.debian.org/debian-ruby/2025/07/msg00000.html

mmdebstrap

• Started to work (locally) on filling up the MIR: Bug #2087937 “[MIR] mmdebstrap” : Bugs : mmdebstrap package : Ubuntu
  That unfortunately didn’t go too far, as mmdebstrap’s testing is close to non-existing on Ubuntu. That would need to be addressed before going further with the MIR.

Oracular EoL

Error Tracker

• Worked with IS to get an environment for the main parts (not the retracers), to start charming it and redeploying out of PS5.
