[Edwin Harris]

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.
