[Bug 2064211] [NEW] /usr/bin/update-manager:AttributeError:<lambda>:available:start_available:refresh_cache:_get_ua_security_status

[errors.ubuntu.com bug bridge]

Public bug reported:

Looks like ua.updates() can actually throw an exception. Only that would
explain this crash.

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/UpdateManager/Dialogs.py", line 118, in <lambda>
    button.connect("clicked", lambda x: callback())
  File "/usr/lib/python3/dist-packages/UpdateManager/Dialogs.py", line 371, in available
    self.window_main.start_available(error_occurred=True)
  File "/usr/lib/python3/dist-packages/UpdateManager/UpdateManager.py", line 242, in start_available
    self.refresh_cache()

    self._get_ua_security_status()
  File "/usr/lib/python3/dist-packages/UpdateManager/UpdateManager.py", line 285, in _get_ua_security_status
