I had some programs that use PyQt5. If create a Snap of it and try to start it, it will not work and pritn this error message: qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, xcb, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl. Abgebrochen (Speicherabzug geschrieben) The solution is, to use the PyQt5 stage package. It would be nice, if I can use the pip package, because it's more up to date.
