Title:
  Upon inserting Ubuntu liveCDs older than current install, it still
  asks to upgrade

Status in “update-notifier” package in Ubuntu:
  Fix Released

Bug description:
  [Impact]

  Just a little problem, with every livecd inserted it propose to
  upgrade, although it is a release older than the installed.

  People might accedentally start an "upgrade" with an older version
  medium. Especially if a user has many images around an burns/mount
  unintentionally an older version, and then gets offered an update but
  will receive a downgrade.

  [Test Case]

  mount a cd/usb stick with an older ubuntu version (I used alternative
  install CD) and see how it offers an upgrade from that media.

  After applying the change in the branch to the file /usr/lib/update-
  notifier/apt-cdrom-check the error is fixed.

  [Regression Potential]

  The fix was developed by 3 developers and consists only of 4 code
  lines. So it should be free of errors now.

  If there is an undiscovered bug in that code now, it will cause, that
  no update dialog comes up anymore, even if a media with a newer Ubuntu
  Version is mounted.

  [Other Info]
   
  Another way to test the fix is to execute the script directly by
  /usr/lib/update-notifier/apt-cdrom-check /media/path/to/the/ubuntu/cd/or/usb/media

  and then check the return value of that script with
  echo $?

  1 = CD with packages
  2 = Ubuntu CD with newer version that the currently installed

  After the application of the patch it returns only 2 if the inserted
  media is indeed newer.
