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, xcb.

Aborted (core dumped)

Yes, I get that apparently Qt is to blame. But still I'm not sure what exactly the problem is, considering literally five minutes earlier it didn't exist?

To quote from Kovid Goyal's response to someone who had a very similar error.

I'm running Zorin Linux, and have been on Calibre 4.x. I missed the jump to 5.0, but when I upgraded to 5.0.1 and tried running it, I got the following error message:

I tried re-installing, but had no joy- I still got the same error message.

Any ideas?
