  • subiquity
    • PR: 1370 (LP: #1767054) - move keyboard layout suggestions to data file, and add script to help generate that data. Refresh the language list, a data file that is generated on build, and use that to add a few more keyboard layout suggestions.
    • PR: 1371 - one part of a fix for an issue with the IDs assigned to partitions. They looked like reasonable display labels but could contain a number that was not actually the partition number.
    • PR: 1373 - fix case where Subiquity would offer to put an ESP on a logical partition, which is known to not work per LP: #1796260
    • PR: 1374 - merge below curtin fix
    • As part of review of PR: 1359, cloud-init schema validation improvements for subiquity, investigated autoinstall failures in user-data that are causing block probing to fail. This seems to represent some wider bug in subiquity itself, unrelated to that PR. Holding merge for now until this is understood.
    • (no PR yet) - examining guided partitioning and handling of a finite number of primary partitions. Are there guided cases that can be salvaged by creating an extended? (yes)
    • Review PR: 1347, 1359, 1375, 1376
  • curtin
    • MP: 427643 - do a better version of the kname lookup for arbitrary devices
    • Review MP 427671 about curtin incremental invocation
  • livecd-rootfs
    • MP: 427445 - refine config to let cloud-init know about network-manager

subiquity does not format the partition when needed:

  • finalized MIR: #1980968 libregexp-wildcards-perl (needed for lintian) by making the test-suite run at autopkgtest time. Patch applied in Debian and synced to Ubuntu (with other nice packaging updates that the maintainer included in the new version. Waiting on archive admin to promote the package.
