The document can say for an error like above :
in the output grub-common failed to install because the service failed to restart which edits the /boot/grub/grubenv file. This indicates the file is corrupted either due to a bug in grub we don't know about, a hard reset during grub running which corrupted the disk cache or something like that, or the drive is failing.

My suggestion is to perform a drive check and delete the file to solve the issue.

Might free up sometime as fewer invalid bugs will be filed by noobs like me

Not able to wishlist importance, can someone with permission do that?
