[Augie J]

Public bug reported:

On Ubuntu 25.10 (Questing Quokka, development branch), running update-
manager crashes when refreshing the package cache. This prevents the
graphical updater from functioning.

Run
  update-manager -c

Expected Result

Update Manager should refresh the package cache and display available
updates.

Actual Result

Update Manager crashes with a Python traceback.

Relevant Traceback

TypeError: GioUnix.DesktopAppInfo.get_filename() takes exactly 1
argument (0 given)
