  • subiquity
    • PR: 1628 - one more environment fix for running netplan
    • PR: 1633 - address LP: #2012921 + many duplicates, for autoinstall and Desktop. Allows one to use LVM+LUKS and have the rootfs expand to use the remaining VG space. Current scaled free space behavior is unmodified for Server, and for autoinstall if the new keyword is omitted.
    • PR: 1634 - restructure how info about bootable disks is provided, in hopes of addressing some crashes when attempting to mark a disk that is full as bootable. May need further iteration with Desktop.
    • PR: 1636 - Address an issue where the ESP was inappropriately reformatted because we had failed to collect filesystem information. Getting filesystem types is now considered bare-minimum information to proceed to the storage screen.
    • PR: 1629, PR: 1635, PR: 1638 - Merges to the ubuntu/lunar stable branch
    • WIP: localectl the live session on locale POST, more probert diagnostics
