> BTW, the grub-efi-amd64 and grub-pc conflict in d/control. I think the
grub-efi-amd64 should also be supported in some non-grub-pc cases.

That is expected, those are control and not binary packages. For the
normal amd64 setup we use grub-pc as the control package, that way efi
amd64 grub can still be installed by the postinst of grub-efi-
amd64-signed, and thus it is possible to have a dual BIOS/UEFI boot
setup.

Title:
  [3.0][bug] Missing a 'grub-install' settings for classic image

Status in Ubuntu Image:
  Fix Committed

Bug description:
  Hi,

  We found if the classic image, which is generated by ubuntu-image 3.0,
  uses grub-efi as its boot assets, the classic environment can't update
  its shim.efi and grub.efi files correctly by "sudo apt upgrade".

  Because its grub Debian package manifest settings are not correct.
  Please reference the description from livecd-rootfs: https://git.launchpad.net/ubuntu/+source/livecd-rootfs/tree/live-build/buildd/hooks/02-disk-image-uefi.binary?h=applied/ubuntu/jammy-devel#n101

  Could ubuntu-image 3.0 support to setup correct grub Debian package
  manifest?

  [Reproduce steps]
  1. Build an amd64 classic image that uses grub-efi boot assets
  2. Bootup image and make sure there is a newer shim-signed and grub-efi-amd64-signed
  3. "sudo apt update" and "sudo apt upgrade" to update newer shim-signed and grub-efi-amd64-signed
  4. Check the checksum result for /boot/efi/EFI/ubuntu/shimx64.efi and grubx64.efi
  5. The checksum result still the old version, not newer version
