Just does nothing on Xubuntu 18.04

Just does nothing on Xubuntu 18.04, just exits.

Works fine in Fedora 30. I suppose for Ubuntu users, the official deb package is the one to use. For me on the other hand, this works great although it is just running the parsecd command without any argument options like app_daemon=1 which I like to use from time to time. I'm just glad appimage is an option even if it is unofficial.
