Steps to Reproduce

1. Install a new docker-calibre-web with with docker version linuxserver/calibre-web:0.6.9-ls83
2. Follow the guideline to initialize everything
3. Use /usr/bin/ebook-convert in Basic Configuration -> External binaries -> Path to Calibre E-Book Converter
4. Try to convert an AWS format file to PDF format.
5. Find the failure in the logging

Steps to Fix

I don't know whether ebook-convert do rely on X11 or not but after I installed the libs the errors are gone.

1. apt install -y libxi-dev

Environment

OS: Ubuntu 18.04 HWE
Arch: x86_64

Thanks for opening your first issue here! Be sure to follow the issue template!

[davosian]

Installing libXi with apt install -y libxi6 worked as well.

@davosian Just came to say that!

Shouldn't need the dev package. Have pushed a fix for this and confirmed the issue and fix is working locally.

I think @adamcavendish means AZW3 rather than AWS as well
