[Bug 1767942] [NEW] package grub-efi-amd64 2.02-2ubuntu8 failed to install/upgrade: installed grub-efi-amd64 package post-installation script subprocess returned error exit status 1

[Sondre Kjellmann]

Public bug reported:

Upgraded from 16.04 to 18.04. When I came back, the login screen for
18.04 was present, but there was no password field, so I had to ctrl +
alt + f1 and ran the command "nohup unity --replace &" to login.
