Title:
  apt-get  installs grub-pc package 2.02-2ubuntu8.21 without errors, but
  the machine fails to boot

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  We are creating AWS AMIs using an EBS surrogate and running this
  command which completes successfully without any errors (only specific
  package shown):

  Distribution: bionic

  apt-get install -y --no-install-recommends grub-pc

  Afterwards when we check the /grub directory it is incomplete:

  ls -l grub/
  total 2348
  -rw-r--r-- 1 root root 712 Jan 26 08:18 gfxblacklist.txt
  -rw-r--r-- 1 root root 2397557 Jan 26 08:18 unicode.pf2

  An instance created using the AMI also fails to boot with the
  following error:

  No bootable disk

  The grub-pc version installed is 2.02-2ubuntu8.21.

  If we install grub manually using grub-install and grub-mkconfig it
  works with the same version (2.02-2ubuntu8.21).

  The above mentioned automated AMI creation process running apt-get
  also works if we downgrade to version 2.02-2ubuntu8.17.

  Previously we created images with version 2.02-2ubuntu8.18 (as that
  was the current version at the time) and it worked perfectly, but we
  noticed that this has been removed from the Ubuntu archive:
  http://archive.ubuntu.com/ubuntu/pool/main/g/grub2/ (only
  2.02-2ubuntu8.17 and 2.02-2ubuntu8.21 still available).

  From the changelog it seems likely that the breaking change could have
  been introduced here:
  https://launchpad.net/ubuntu/+source/grub2/2.02-2ubuntu8.19
