Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual
for more information.

Qt GUI wanted but not found, falling back to ncurses.

Something is wrong with the YaST user interface.
is that same with window manager (plasma 6) ?
yast can now open i really don’t know how, I wiped out “selinux” at grub kernel parameters…
don’t give a f*** about that stuff
but now I can’t start any session with init 5 (multi user and GUI)
This reads like you have more problems than just setting locale. For further clarification, is this a fresh Leap 16 installation or did you upgrade from an earlier release? If it’s a fresh install using the Agama installer, and did you select a desktop environment during installation? Also, when you say you can’t start a graphical session with init 5, what actually happens? Does a graphical login screen appear, do you get a black screen, or does it return to the console?
