Installed from 18.04.4 media, in bios mode.

Added and loaded apparmor profile.

Enabled focal, focal-updates, focal-proposed archives.

Exported DEBIAN_FRONTEND=noniteractive to ensure non-interactive updates.

Started upgrade of grub-pc grub-pc-bin grub2-common grub-common.

Configuration of grub-pc 2.04-1.ubuntu26.4 failed (GOOD) iF state

in /boot/grub git diff shows only one change => fonts/unicode.pf2 has changed. (not ideal, but nothing else important has changed, i.e. all modules are the same and modinfo.sh still says 2.02-2ubuntu8.18 as the package version) (GOOD)

executed
echo grub-pc grub-pc/install_devices multiselect /dev/sda | debconf-set-selections
to set install_devices to invalid /dev/sda, instead of the correct /dev/vda for the next test case. And removed the apparmor profile.

Reboot. Still worked (good)

exported DEBIAN_FRONTEND=noninteractive, and attempted to configure all the packages with dpkg --configure -a

configuration/installing onto /dev/sda failed (GOOD). No further changes in /boot (GOOD). Reboot works. (GOOD)

Finally performing dpkg --configure -a worked, got asked which drive to update, elected the correct /dev/vda and all modules got updated in the /boot/grub dir. Reboot works. (GOOD)

Just to be sure, executed dpkg-reconfigure grub-pc and all questions got asked and grub got installed onto /dev/vda again. (GOOD)
