[Bug 2038401] Re: package grub-efi-amd64-signed 1.187.6+2.06-2ubuntu14.4 failed to install/upgrade: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 32

[Koen Roggemans]

I updated a device through the graphical interface (they all do
automatic cli upgrades, which fail).

I got a screen, showing the help pop up:

"The GRUB boot loader was previously installed to a disk that is no
longer present, or whose unique identifier has changed for some reason.
It is important to make sure that the installed GRUB core image stays in
sync with GRUB modules and grub.cfg. Please check again to make sure
that GRUB is written to the appropriate boot devices."

And then only /dev/nvme0n1p1 to choose from to install grub.

Am I correct that the system expects to find grub on another location,
can't find it, and then suggests the only possible location?

Probably something changed in the process of imaging. Is there a way to
make this more robust?
