Title:
  package grub-efi-amd64 2.00-7ubuntu11 failed to install/upgrade:
  ErrorMessage: subprocess installed post-installation script returned
  error exit status 1

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  The package grub-efi-amd64 fails to configure itself. The root cause is 'update-grub', which fails with exit code 1.
  However it only fails when my external drive is connected, a WD My Book 1130 (3 TB pure-4k drive, i.e. no 512 B sector emulation).

  I researched further and found that it only fails when my OS X 10.9
  (currently at Developer Preview 8) system partition (HFS+) is mounted.
  If I unmount this HFS+ partition, update-grub finishes successfully.

  Output with OS X Mavericks partition on pure 4k drive mounted:

  There is an additional error message when the OS X 10.9 partition is unmounted: 'grub-probe: fel: okänt filsystem' (means: grub-probe: error: unknown filesystem' in English).
  I don't know how to get more debug output from update-grub.
