I've tried to install The Powder Toy through the gnome-software center. It shows as if it was installed. Proof:
If you don't understand what happens, when I click "Eliminar", in the installed menu, some powder toys pop up. And if I delete them, nothing happens. Not even file delition. Tried to reinstall the gnome-software package, but nothing. Is this a problem with gnome-software, the powder64 app, both or just my OS'?
