[Bug 1800106] [NEW] package grub-efi-amd64-signed (not installed) failed to install/upgrade: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1

[Mohammad Reza Yousefi]

Public bug reported:

I was installing ubuntu but at the ending part it showed an error about
grub boot loader install failure. I tried "boot-repair" tool using the
live system and it seemed to be fixed but after restarting the system I
had an error message that says grub still has problems...
