Rust

  • Requested Focal rustc-1.82 upload from Security.
  • rust-defaults migration is waiting on a rust-sudo-rs MP which removes the offending autopkgtests.
  • rustc-1.86 update:
    • Fixed several miscellaneous build issues.
    • Raised i386 baseline to include SSE2.
    • Did some d/copyright housekeeping, cleaning up the file in general.
    • rustc-1.86 now builds on all platforms except ppc64el. I’m currently working on that issue.

Maintainer Tools

  • Updated dh-cargo MP according to Simon’s review
  • With the help of AI, I created two automation scripts to list redundant and unneeded d/copyright stanzas in rustc

Questing

  • Uploaded A/B boot implementation (LP: #2116266):
    • Pending AA review as it includes a new package (flash-kernel-piboot)
    • Update the raspi platform seed
    • Update the pi-gadget to conform to the new boot partition layout (PR pending)
  • Uploaded new ubuntu-raspi-settings for questing:
  • Merged changes to the image definition yaml to fix the filenames (forgot this when updating plucky->questing!)
    • Thanks to @utkarsh for the quick review!
  • Merged changes to slim down the Ubuntu Desktop for raspi images (base on desktop-minimal, not desktop) (LP: #2103808)
    • Prepped and tested an updated image definition (which, for some reason duplicates the seed names) to see how much this actually slimmed the image (~777MB it turns out)
    • Thanks again to @utkarsh for the rapid review!
    • Uploaded updated ubuntu-meta
    • Updated questing release notes to warn upgraders that some “common” applications may disappear on upgrade (but can be easily reinstalled)

Plucky

  • Rejected the old slimmed-down branch for plucky as that didn’t make it in time for release (LP: #2103808)
  • Sponsored flash-kernel db addition for @xypron (LP: #2116161)
