[Bug 1595154] [NEW] Wrong result/count in update-notifier depending of the python version

[Hassan El Jacifi]

Public bug reported:

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:
