Title:
  Sometimes update-manager hangs and the user has to force its shutdown

Status in update-manager package in Ubuntu:
  New

Bug description:
  Under Xubuntu 20.10, I checked for some updates launching update-
  manager with a terminal, and then switched to another software,
  leaving update-manager open.

  When I wanted to close update-manager by clicking on OK, it hanged, so
  I was forced to close it by using ctrl-c on the terminal window.

  This is the traceback I got as soon as update-manager closed:

  ~$ update-manager
  WARNING:root:can not import unity GI Namespace Dbusmenu not available
  ^Clsb_release returned exitcode: -2
  Traceback (most recent call last):
    File "/usr/bin/update-manager", line 119, in <module>

      return _Gtk_main(*args, **kwargs)
