Title:
  package grub-efi-amd64 2.02~beta2-36ubuntu3.11 failed to
  install/upgrade: subprocess installed post-installation script
  returned error exit status 2

Status in grub2 package in Ubuntu:
  New

Bug description:
  It seems to have started happening after denying from a script to
  disable safe booting. The reason why I did this was that nvidia
  drivers malfunctioned otherwise. I do not know if this is the real
  cause, but I observed it after this action. Also, in conjuction with
  this bug, I have observed high cpu usage from apport, before the above
  error appearing on the screen.
