21.12.1
- Fix a packaging issue where importing ssh keys and detecting distribution information failed on 18.04 and 20.04 installs (this is why the previous release did not get released to the stable channel)
- Improve how subiquity merges lists when combined autoinstall-supplied and internally generated cloud-config. This means that specifying a user under "identity" and also in "user-data" in the autoinstall config works as expected.
- Update curtin:
- Fix installs of jammy (where lsblk changed output)
- Install shim-signed on arm64 UEFI systems
- The Apt components 'universe', 'multiverse', and 'restricted' may be disabled via autoinstall. Sample usage:
apt:
