[Bug 1753518] Re: package grub-efi-amd64-signed 1.93+2.02-2ubuntu8 failed to install/upgrade: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1

[Mathieu Trudel-Lapierre]

Please read this until the end before commenting. I am closing this bug
as "Invalid", because we can't deal with the many different types of
problems seen by people all on this same bug report.


This is, for most users, a firmware issue (in which case, if you're running a Dell laptop, please check with Dell if firmware updates exist. This is especially true for Dell XPS 13 (9343)). We will be tracking this (Invalid argument, followed by "Block device required" error messages) on bug 1805490.

If you are getting an "Input/output error"; please file your own NEW bug
report, and make sure to include the output of  "sudo efibootmgr -v". We
will ask you for more information on your own bug.

If you are getting "No space left on device"; please file your own NEW
bug report, and make sure to include the output of "ls -l
/sys/firmware/efi/efivars". We will ask you for more information on your
own bug.

If you are getting "grub-install: error: cannot find EFI directory.",
you have likely modified your installation in some way. Please file your
own NEW bug report, we can walk you through fixing this.

If you are getting any other kind of error not listed above; as for
everything else, please file a your own NEW bug report, so we can figure
out exactly what your problem is, not "guessing" based on what others
may have commented.

And above all, please do not follow random comments by people on bug
reports claiming they have workarounds. These may further complicate
things, it makes it very hard for developers to understand what is going
on and be able to fix bugs.
