[Bug 1928674] Please test proposed package

[Łukasz Zemczak]

Hello Dimitri, or anyone else affected,

Accepted grub2-signed into bionic-proposed. The package will build now
and be available at
https://launchpad.net/ubuntu/+source/grub2-signed/1.167~18.04.3 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-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. 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]

   * /etc/kernel/{postinst.d,postrm.d}/zz-update-grub missing on arm64
  with grub-efi-arm64 (a dependency of grub-efi-arm64-signed) installed

   * /etc/kernel/{postinst.d,postrm.d}/zz-update-grub missing on amd64
  with grub-efi-amd64 (an ORed dependency of grub-efi-amd64-signed)
  installed.

   * This results in newly installed kernels not getting added to
  grub.cfg and thus upon reboot one does not boot into the new kernel.

   * In later series these scripts moved to grub2-common, which is why
  they are absent in the backported grub-efi-* packages.  They should be
  restored to these packages in the backport.

  [Test Plan]

   * Install new grubs

   * If testing on amd64 ensure that grub-efi-amd64 is installed, not
  grub-pc.

   * Install a new kernel that was not installed before

   * Observe that grub.cfg is regenerated and new kernel is present

   * Remove an old kernel

   * Observe that grub.cfg is regenerated and new kernel is removed from
  grub.cfg

   * From bionic, verify that a dist-upgrade to focal works without
  conflicts.

  [Where problems could occur]

   * These are conffiles. Although nobody should modify them, care
  should be taken when moving conffiles around.

  [Other Info]

   * First reported by klebers
