[Bug 1880987] Re: /usr/bin/update-manager:TypeError:_on_finished:_action_done:get_deb2snap_dups:_on_finished:_action_done:get_deb2snap_dups

[Brian Murray]

Here's the Traceback:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/UpdateManager/backend/InstallBackendAptdaemon.py", line 236, in _on_finished
    self._action_done(action,
  File "/usr/lib/python3/dist-packages/UpdateManager/backend/__init__.py", line 319, in _action_done
    self.window_main.duplicate_packages = self.get_deb2snap_dups()
  File "/usr/lib/python3/dist-packages/UpdateManager/backend/__init__.py", line 125, in get_deb2snap_dups
    if (deb in cache and cache[deb].is_installed):
TypeError: argument of type 'NoneType' is not iterable

During handling of the above exception, another exception occurred:

  File "/usr/lib/python3/dist-packages/UpdateManager/backend/InstallBackendAptdaemon.py", line 244, in _on_finished
    self._action_done(action,
