[Bug 2052643] Re: upgrading to 23.10 failed package grub-efi-amd64-signed 1.197+2.12~rc1-10ubuntu4 failed to install/upgrade: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1

I suggest closing this bug report. I think there's a bug in how the GRUB
configure scripts handle this kind of error but it's unrealistic
anyone's going to fix it in this old version. I've given up trying to
upgrade my system.

FWIW I managed to get dpkg to reconfigure and find a new path for GRUB.
I didn't do this carefully (I was trying suggestions from an AI) but I
seem to have successfully convinced GRUB to stop using the old
/dev/disk/by-id/ path and use /dev/vba1 instead. It picked this path on
its own.

$ echo "grub-efi grub-efi/install_devices select" | sudo debconf-set-selections
$ dpkg-reconfigure grub-efi-amd64

After doing this I could reconfigure grub-efi-amd64 and reboot with no
problems. GRUB seems to be working in 23.04. I then did an apt full-
upgrade to 23.10 which looked like it worked (I had to hack this update
without do-release-upgrade.). But then the system failed to boot, the
UEFI BIOS didn't like whatever it found for GRUB. I don't know if that's
because I screwed up something else or my GRUB config is to blame.
