I did this on Mint 20.1 and it was fine

Code:

Run "calibre" to start calibre 
quoth@Morag ~ $ calibre
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

I did upgrade all the normal plugins, removed DeDrm 6.x and removed any other plugins that seemed likely to be a problem, or can only be updated after updating Calibre.

I took screen shots of plugin and copy/pasted serial numbers. I used that for the upgrade on the 20.1 system. Tested with some original Amazon downloads. Then copied my existing library, switched libraries and everything is OK.

So something missing on Mint 18.3, or is it an actual plugin is the problem?
