thank you for your bug report, did you forget to include the output for
the upgrade command or does it return nothing?

Title:
  Wrong result/count in update-notifier depending of the python version

Status in update-notifier package in Ubuntu:
  New

Bug description:
  Hi Guys,

  I have seen a strange behavior regarding the update notifier. Our
  monitoring system isn't able to show missing updates.

  After starting looking closer, the script apt-check is not providing
  the correct result depending the python version. Changing python from
  3 to 2 or changing the shebang solve the issue.

  Details:

  root at xx ~ # ls -al /usr/bin/pytho*
  lrwxrwxrwx 1 root root       9 Dec 21  2013 /usr/bin/python -> python2.7
  lrwxrwxrwx 1 root root       9 Dec 21  2013 /usr/bin/python2 -> python2.7
  -rwxr-xr-x 1 root root 3345416 Jun 22  2015 /usr/bin/python2.7
