[Bug 1356823] Re: aptd crashed with AttributeError in _remove_from_connection_no_raise(): 'NoneType' object has no attribute 'Destroy'

[Jeffrey Tees]

Occured on login to unity.

After kubuntu-desktop install (reconfig to sddm which failed next reboot
+ replaced lightdm as display-manager)

Subsequent reboot & login resulted in error message about sddm not
installed & this error.
