[Bug 1031680] Re: check_apt always report 0 critical updates

[Robie Basak]

It looks like this is due to how check_apt is checking for "critical"
updates. Since Ubuntu publishes security updates in both the -updates
and -security pockets, it only works if the security pocket is listed
first in sources.list.

Workaround: move the security lines in /etc/apt/sources.list to the top.

Now I get:

ubuntu at precise-test:~$ /usr/lib/update-notifier/apt-check --human-readable
17 packages can be updated.
12 updates are security updates.
ubuntu at precise-test:~$ /usr/lib/nagios/plugins/check_apt
APT CRITICAL: 14 packages available for upgrade (9 critical updates). 

Not an exact match, but better. This is probably due to how exactly
check_apt is checking apt-get's output.

It seems suboptimal to me. Now that /usr/lib/update-notifier/apt-check
exists, check_apt could use it instead. But this would be a fundamental
change in how check_apt works, so this should probably be sent for
discussion upstream.

Changing to Importance: Medium as a workaround is available.
