My inventory is filled with trash, which I don't need, but I can't sell it. It just doesn't happen. When I try to sell, the game thinks I am trying to repair. Can't discard either. When the game asks if I am sure, if I press '2' (no) it accepts my response, but if I press '1' it just ignores it, as if I didn't press it!!
Actually I was able to discard one single item, but this item was consumable, and I am not able to discard e.g. armours, weapons, item debris !!!!!

I am also a linux user, could this be a linux bug?
