Comment 3 for bug 503649

I updated the bug description to remove a bogus reason I'd like to see updated AMIs. There is no bug in the grub-pc package update code; the mistake was mine.

For anybody who saw the original report, I was simply missing the -E option to pass environment variables to a sudo command:

  export DEBIAN_FRONTEND=noninteractive
  sudo apt-get update
  sudo -E apt-get upgrade -y

That said, I still think it's a great idea to publish updated AMIs.
