'Slightly' back-
(1) the GUI from 'system'network' now lists a wired connection
[not there before] but it is labeled 'Unmanaged' and no way to make
changes with that GUI.
(2) there is now a wireless-looking small icon top right of screen [not
like the original icon]. 'wired network' is grayed out. 'connection
info' gives err msg "no valid active connections found". 'edit
connections' box does come up, listing a wired connection that was
supposedly used 4 days ago, even though it was used just minutes ago. 

So - some GUIs are back but with wrong info and no ability to do
settings. But, maybe that's progress... :-))

start: Job is already running: network-manager

Nothing changed by doing this
