calibre run issue
Hello I have been struggling a quite long time to install calibre on my ubuntu EC2 machine
But It returns the following error
calibre
qt.qpa.xcb: could not connect to display
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: linuxfb, minimal, offscreen, vnc, vkkhrdisplay, xcb, wayland-egl, eglfs, wayland, minimalegl.
Aborted (core dumped)
I have try all command
sudo apt install libxcb-xinerama0
export QT_DEBUG_PLUGINS=1
but did not get any success this is working fine in local machine but not working on ubuntu live server and digital ocean server as well
