| Yes, I did that and removed plasma-discover-updater and that resolved the error, then I did a successful full-upgrade and let it remove an additional 7 packages: 
       Code: 
Remove: libnih-dbus1:amd64 (1.0.3-5+b1), libcgmanager0:amd64 (0.41-2), libnih1:amd64 (1.0.3-5+b1), libkipi-data:amd64 (4:15.08.3-2), libkipi11:amd64 (4:15.08.3-2), cgmanager:amd64 (0.41-2), plasma-discover-private:amd64 (5.6.5-1)
End-Date: 2016-09-03  12:56:23
 The upgrade also brought appstream back because I have plasma-discover installed.
