Hey,
when I start my python3 qt5-application, I got this message:
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
qt.qpa.plugin: Could not load the Qt platform plugin "wayland" 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, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb, wayland-org.kde.kwin.qpa.
My dup is up to date (kernel 5.2.2.1-default), I use plasma5 with xorg, not wayland. libxcb and libwayland exist in /usr/lib64/qt5/plugins/platforms - I created a symbolic link to /usr/bin (similar to the same problem in ubuntu), but didn’t work out for me.
Any ideas?
Thx, reiti
