Can't save interface options and change theme

I was using Musescore 2.0 from kxstudio repo, and then I upgraded to 2.01.

Now I cant set the dark theme nor save the opened scores.

Musescore doesnt remember any of the change I make.

I think it may be related to permissions but I cant find the solution.

here is the log when i run musescore -d
