Title:
  package grub-pc 1.99-21ubuntu3.1 failed to install/upgrade:
  ErrorMessage: subprocess installed post-installation script returned
  error exit status 143

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  During the upgrade to 1.04 the installation package hung after trying to generate the grub.cfg file. 
  The update manager output listed all found packages, got to memtest and stopped.

  I cleared the stop by looking at the 'ps aux' command output and killed the 'grub-mount' PID  and this let the update continue.
  This happened 3 times during the install, presumably because the grub install was not complete.

  Finally the install finish and reported that 'grub-pc' couls not be
  installed. and after the cleanup would not reboot from the update
  program. I killed the update and restarted manually.

  Luckily grub worked on reboot and had picked up 12.04 and the 3.2.0-25 kernal and generated this bug report.
  Its 3am now so I am not going to try apt-get for grub.

  Thank  you
  Steve
