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

[Andreas Hasenack]

Hello Mate, or anyone else affected,

Accepted cd-boot-images-amd64 into jammy-proposed. The package will
build now and be available at https://launchpad.net/ubuntu/+source/cd-
boot-images-amd64/20.4 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

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.
