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

[Hassan El Jacifi]

Hi Guys,

I don't know if the bug affect 16.04 too.

The result is shown after the command apt-check. As you can see when you run it with:
- python3 you have 0,0 that means no package to update.
- python2 you have 4,0 that means 4 packages to update.

Start-Date: 2016-06-22  15:03:38
Commandline: apt dist-upgrade -uV
Upgrade: grub-common:amd64 (2.02~beta2-9ubuntu1.7, 2.02~beta2-9ubuntu1.8), grub2-common:amd64 (2.02~beta2-9ubuntu1.7, 2.02~beta2-9ubuntu1.8), grub-pc-bin:amd64 (2.02~beta2-9ubuntu1.7, 2.02~beta2-9ubuntu1.8), grub-pc:amd64 (2.02~beta2-9ubuntu1.7, 2.02~beta2-9ubuntu1.8)

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:
