  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:
  Confirmed

Bug description:
  I have two EFI partitions for redundancy, e.g. /boot/efi-4404-576D and
  /boot/efi-4490-1C3D

  The auto-configure UI recognises these but the install script appears
  to fail because there is no /boot/efi
