I tried the earlier 2016-12-26 version and was happy enough with the software to opt for the std version. The only problem (temporarily resolved by using the std older version which, luckily I kept) is that I can’t get 17.5.5 to start on my pcs.
I think I can narrow this down to the client portion but at present can’t offer much else in the way of feedback. If I try to start in a terminal, the result is a lock up that ctrl C will not break out of. There are no error messages or other feedback.
Systems tried are OpenSUSE Leap 42.1 and 42.2 both using the Plasma5 desktop.
