Public bug reported:
The on_driver_selection_changed method in SoftwarePropertiesQt.py was
incorrectly ported from the GTK frontend, preventing driver
installation.
Qt's toggled signal passes a bool, unlike GTK which passes the widget.
The code used functools.partial to pre-bind arguments, so the bool was
either passed as an extra positional argument (causing a TypeError) or
misinterpreted as a package name (causing a KeyError). The method also
called self.userinterface.sender() to get the radio button, but
self.userinterface is the wrong QObject, so it returns None.
Additionally, a typo ("manually_install" instead of
"manually_installed") caused wrong signal wiring for some buttons.
The net effect is that driver_changes is never populated, so the Apply
button stays disabled and no packages are sent to PackageKit.
Fix: accept the button as an explicit parameter instead of using
sender(), use lambdas instead of partial to absorb the bool from
toggled, and fix the typo.
