[Bug 1965811] Re: software-properties-qt does not load driver information

[Darin Miller]

Not an expert here, but the problem appears to be the import apt line 58
in SoftwarePropertiesQt.py.

apt.Cache() lacks the packages attribute.

Replacing apt with apt_pkg (as seen in the detect.py package and to
which the apt_cache is passed) should fix the problem.

apt is only called twice in SoftwarePropertiesQt.py and both times, it
is used (incorrectly) as follows:

self.apt_cache = apt.Cache()

If this is the correct approach to fix this issue, I will attempt to
submit a patch.
