[Bug 1971165] Re: Upgrade from 20.04 to 22.04 failed due to efi partition naming

I've now managed to recreate this in a checkpointed virtual machine.

The last few lines from do-release-upgrade are:

EFI System Partition (ESP) not usable

Your EFI System Partition (ESP) is not mounted at /boot/efi. Please 
ensure that it is properly configured and try again. 

There is code in /usr/lib/python3/dist-
packages/DistUpgrade/DistUpgradeController.py that matches this message
but I put some diagnostic messages in this file and they weren't
displayed which confuses me a bit.  However that might just be my faulty
understanding of how python works.

Title:
  Upgrade from 20.04 to 22.04 failed due to efi partition naming

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  I recently upgraded a Ubuntu Budgie system from 20.04 to 22.04 the
  upgrade worked fine apart from one problem.

  The original system had two EFI partitions mounted at /boot/efia &
  /boot/efib.   Grub is quite happy with this and updates both.  However
  do-release-upgrade failed early on because EFI wasn't mounted at
  /boot/efi.  I changed the mount points and reran do-release-upgrade
  and everything worked fine,  including installing grub to both EFI
  partitions.

  The evidence collected by report-bug may be of little use because it
  comes from the upgraded system,  not the original.
