I updated my Ubuntu box few days ago to latest version 21.10.
Now, I am getting several errors running well-functioning Pythons software. even the Ananconda Navigator (updated too) isn't working. Here is the error message:
2021-11-24 11:03:24,496 - WARNING linux_scaling.get_scaling_factor_using_dbus:39
Can't detect system scaling factor settings for primary monitor.
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
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, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.
Aborted (core dumped)
Using export QT_DEBUG_PLUGINS=1 I got:
