This bug was fixed in the package software-properties - 0.98.9
---------------
software-properties (0.98.9) focal; urgency=medium
* softwareproperties/gtk/SoftwarePropertiesGtk.py:
- Gtk is doing something that takes a lock while processing checkbox
toggled events, the polkit auth dialog can't be displayed in return,
we don't have a proper fix and it might require GTK changes,
meanwhile we want a working interface so workaround with a sleep

Title:
software-properties-qt: nvidia driver version switch fails
Status in software-properties package in Ubuntu:
Fix Released
Bug description:
Switching the Nvidia driver version with kubuntu-driver-manager
doesn't work anymore: Selecting a different driver version (nvidia-
driver-440 instead of the currently selected / installed -390) and
clicking "Apply Changes" has no effect and produces this error message
in the terminal:
Traceback (most recent call last):
File
"/usr/lib/python3/dist-packages/softwareproperties/qt/SoftwarePropertiesQt.py",
line 895, in on_driver_changes_apply
for dep in get_dependencies(self.apt_cache, pkg.shortname, 'nvidia'):
NameError: name 'get_dependencies' is not defined
Steps to reproduce:
- sudo kubuntu-driver-manager
- Under "Additional Drivers", select a different Nvidia driver version
(in my case: 440 instead of 390)
- Click "Apply Changes"
- (observe error message in the terminal)
Expected result:
- No error message
- Nvidia driver version 440 gets installed
Actual result:
- Error message
- No change in the installed Nvidia driver version
