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)

My deduction seems to be you cant do this on a headless server?
Or you can't run "calibre" in console on a headless server i mean.
Still can't quite figure out how to get this working on headless linux server. Using ubuntu 20.xx

Hello everyone.
I recently did a fresh Xubuntu 22.04 installation and at the moment to install and run calibre (last version 6.0 following the instructions from calibre's webpage) I got the same error message: "qt.qpa.plugingCould not load the Qt platform plugging xcb..."
After install the xcb libraries as you recommended in this topic I still got the same error message.
The solution that works for me:
I remove calibre with the calibre-uninstall command. Then previously having installed the xcb libraries I also installed an app from the repositories that use qt libraries (for example kalzium). After that I installed again calibre from the calibre's webpage and it works perfectly.
I hope it helps someone!!
Thanks for your support. Best regards
