Title:
  grub-install post installation script fails

Status in grub-installer package in Ubuntu:
  Expired

Bug description:
  The grub-install apt upgrade does not complete successfully on my
  system.

  Distributor ID:	Ubuntu
  Description:	Ubuntu 16.10
  Release:	16.10
  Codename:	yakkety

  Kernel: 4.8.0-32-generic
  arch: X86_64

  Here is the error from the apt-get upgrade

  Installing for x86_64-efi platform.
  grub-install: error: cannot find EFI directory.
  dpkg: error processing package shim-signed (--configure):
   subprocess installed post-installation script returned error exit status 1
  Setting up grub-efi-amd64-signed (1.74+2.02~beta2-36ubuntu11) ...
  grub-install: error: /usr/lib/grub/i386-pc/modinfo.sh doesn't exist. Please specify --target or --directory.
  dpkg: error processing package grub-efi-amd64-signed (--configure):
   subprocess installed post-installation script returned error exit status 1
  Errors were encountered while processing:
   shim-signed
   grub-efi-amd64-signed

  I checked into this problem and since my system is not an i386
  architecture there is no i386 directory in /usr/lib/grub directory. Is
  it possible that the post install script does not use the architecture
  properly? I would not expect the post install to call anything from
  the i386 directory on an X86_64 system.

  $ apt-cache policy grub-install
