I'm having trouble running Calibre server on my Debian 11.4 Bullseye system. I've installed the official binaries using the instructions at https://calibre-ebook.com/download_linux

But when I start calibre-server I get this error:

Failed to import PyQt module: PyQt6.QtGui with error: libEGL.so.1: cannot open shared object file: No such file or directory

ImportError: cannot import name 'QImage' from 'qt.core' (/opt/calibre/lib/calibre-extensions/python-lib.bypy.frozen/qt/core.pyc)

My first thought was to install the PyQt6 package, but there doesn't appear to be one available for Debian 11.4.

Any ideas?
