[Bug 1912264] Re: Provide grub 2.04 EFI backport on bionic

[Steve Langasek]

Hello Dimitri, or anyone else affected,

Accepted grub2.04-signed into focal-proposed. The package will build now
and be available at
https://launchpad.net/ubuntu/+source/grub2.04-signed/1.143 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-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. 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.

Title:
  Provide grub 2.04 EFI backport on bionic

Status in grub2.04-signed package in Ubuntu:
  Fix Released
Status in grub2.04-signed source package in Bionic:
  In Progress
Status in grub2.04-signed source package in Focal:
  Fix Committed

Bug description:
  [Impact]

   * Provide grub 2.04 backport to bionic for improved TPM support.

  [Test Case]

   * Boot to bionic EFI amd64 or arm64

   * If /boot/efi/EFI/ubuntu does not exist, execute

   on amd64 $ sudo grub-install --target x86_64-efi --uefi-secure-boot
   on arm64 $ sudo grub-install --target arm64-efi --uefi-secure-boot

  and reboot

   * Install grub2.04-signed on bionic amd64 or arm64

   * Reboot, check that echo ${package_version} shows 2.04

   * Upgrade to focal

   * Observer that upgrade is correct and grub2.04-signed is now a dummy
  transitional package

  [Where problems could occur]

   * One must be able to remove grub2.04-signed & downgrade back to grub
  2.02 based -bin and -signed packages. And binaries in /boot must be
  updated.

   * One must be able to mix&match userspace grub packages tooling from
  release/security/updates/proposed, whilst keeping grub2.04-signed
  installed.

   * One must be upgraded to stock grub2.04 -bin / -signed packages upon
  dist-upgrade to focal.

  [Other Info]

   * Targetted to be installed by default on some cloud images.
