[Bug 2076929] Re: [SRU] Rebuild cd-boot-images-{amd64, arm64} against new shim and grub

[Andreas Hasenack]

It looks like that grub-efi-amd64-signed in jammy-proposed comes from
https://bugs.launchpad.net/ubuntu/+source/grub2-unsigned/+bug/2043084,
which still needs verification, btw.

Title:
  [SRU] Rebuild cd-boot-images-{amd64,arm64} against new shim and grub

Status in cd-boot-images-amd64 package in Ubuntu:
  Incomplete
Status in cd-boot-images-arm64 package in Ubuntu:
  Incomplete

Bug description:
  [ Impact ]

   * Microsoft is rolling out SBAT revocations via Windows update such that
     single-boot machines with Windows won't be able to boot shim executables
     with SBAT level less than shim,4.

   * For the 22.04.5 media we would like to include the 15.8 shim so that
     it is bootable on such machines.

  [ Test Plan ]

   * Ensure that the resulting cd-boot images contain our 15.8-0ubuntu1 MS UEFI
     CA signed shim executable.

  [ Where problems could occur ]

   * Impact is limited to media built using the new cd-boot images which will go
     through the usual rigorous QA process.

   * The shim and grub that will be used as part of this process will be in the Jammy
     archive before being part of media.
