Binary package “python3-packagekit” in ubuntu trusty

PackageKit backend Python bindings

 PackageKit allows performing simple software management tasks over a DBus
 interface e.g refreshing the cache, updating, installing and removing
 software packages or searching for multimedia codecs and file handlers.
 .
 This package provides PackageKit Python bindings which are still needed
 by some PackageKit backends written in Python.
 If you want to use PackageKit from Python and don't write a backend, please
 use the GIRepository instead.
