Title:
  package grub-efi-amd64-signed 1.128.2+2.04-1ubuntu12.2 failed to
  install/upgrade: installed grub-efi-amd64-signed package post-
  installation script subprocess returned error exit status 1

Status in grub2-signed package in Ubuntu:
  New

Bug description:
  This may be firmware bug.

  This commonly happens on Intel S5520HC, HCV and HCT motherboards. It's
  dual LGA1366 system, and this happens only in UEFI mode. Legacy works
  fine. I suspect BCD region in UEFI is marked read only, so grub and
  shim install fails. On this board I have to manually add boot entry
  and path to EFI executable.

  It's also impossible to completely install Ubuntu on this.

  Affects Intel's S5520UR, and WillowBrook systems.
