Well, upgrading 2850 packages toke for ever, not much to download as much to upgrade the old Sana .
The result was as i expected , very buggy , extremely unstable and the sound system would not start on both Alsa and Pulse .
I think that many files were deleted during the upgrade since the new rolling release is only 2.6 GB , when the old Sana was 3.3 GB.
So i opted for a new install !! so far so good , Gnome is still unstable and freezes constantly .
I installed Mate DM cause it is lightweight and stable .
I will test the applications now and if i see any issue , i will try to fix it and then i will post the how-to.Screenshot :
