Just installed Calibre 7 using the normal wget "Binary install" instructions for Ubuntu 22.04 upgrading from the last 6 release.
It fails to start:
Code:
qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.
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, minimal, minimalegl, linuxfb, offscreen, wayland-egl, wayland, vnc, xcb, vkkhrdisplay.
Aborted (core dumped)
