Bug description:
  I have recently rearranged my hard drives, adding an nvme drive as my
  master boot and removing two sata HDDs.  The old master boot SSD is
  now a backup drive but still contains a bootable partition.

  After an absence of 4 weeks where the system was running I logged in
  to find software updater listing outstanding updates and a message
  saying that "Snap"snap-store" is refreshing now!". I clicked update
  now, which it did and then presented another list of software to
  update.

  During this second software update the system was configuring grub-
  efi-amd64-signed, a window opened listing my two remaining drives
  asking me to tick "GRUB install devices". I twice ticked the nvme
  drive and then next and it asked whether I wanted to "continue without
  installing GRUB?" I left this unticked then next and it took me back
  to the first screen. The third time I ticked both drives then next and
  it initiated this crash report.  I do not know what the error exit
  status was as it was not displayed.

  On a second, identical, system same scenario but this time the grub
  update was part of the first software update and again I ticked only
  the nvme drive but then ticked continue without installing GRUB and it
  went through to completion, again bringing up a second list of
  software to update.

  One difference between the two systems - the Snap store message on the
  system that failed had an icon to the left showing a no-entry sign
  whereas the second system this icon showed an origami bird.

  After the second update the second system requested a reboot which I
  did and it completed successfully.

  Both systems as Ryzen 9 3900 running Ubuntu 22.04.2 LTS, the first
  system having 64GB ram and the second system having 16GB ram.
