Public bug reported:

Somehow the detect_drivers subprocess is reporting exitcode=None after
join(), which we did not expect and is thus raising an exception, which
was caught by errors.ubuntu.com:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 1414, in detect_drivers
    raise Exception(f"Exit code: {self.search_process.exitcode}")
Exception: Exit code: None
