I tried this snap x3 installs to figure out what was going on - (O.K. so I'm a little slow).
I was attempting to do a Core/Hybrid install.
On the first install I got audio/video setup but I never received Sarah.
What I noticed on the second install was that the system was doing a lmce-core install.
O.K. let it run out (because on the first install I tried Graphical Aspect - high to see if it was working) and on the second I went for medium to see if that was the issue.
So, the third time I did medium graphics again and went finished I logged in as root and tried "apt-get lmce-hybrid" - (can't get there from here).
I did an apt-get update & apt-get upgrade. Reboot. Got Sarah, did the Media Player setup. When software was finished downloading did the restart.
Got Flicker and menu.
The volume was very low during audio setup and Sarah so I'll have to probably go into alsamixer to adjust - will advise.
I will try to add my NAS to see if I have the same issue (from about a week ago) with the wget install.
(NAS didn't go to sleep but UpdateMedia didn't do anyrthing until I did a Resynch in webadmin.) - will advise.
