[Bug 1946097] Re: package grub-common 2.04-1ubuntu26.13 failed to install/upgrade: installed grub-common package post-installation script subprocess returned error exit status 1

[Julian Andres Klode]

There seems to be a corrupted /boot/grub/grubenv. A common source for
this can be a hardware defect, or loose cable, or possibly turning off
power while in grub.

Deleting the file and running sudo grub-editenv list while create an
empty file, and allow you to continue.
