Title: upgrade modifies /etc/default/grub inappropriately Status in grub2 package in Ubuntu: New Bug description: If I have: GRUB_CMDLINE_LINUX="nomodeset" in /etc/default/grub, boot hangs with "Failed to start Light Display Manager". No problem, I delete the line and run update-grub. However, running apt upgrade sometimes appends the line GRUB_CMDLINE_LINUX="nomodeset" to /etc/default/grub, resulting in a failed boot after upgrade. I am sure it is appending the line to the file because the rest of the file is unchanged. This has been happening occasionally for a long time. Most recently, it happened when I used do-release-upgrade to go from 18.04 to 20.04 I guess some package thinks it is a good idea to add this option, but I don't know which one, or how to stop it.
