Calibre won't install in Ubuntu Server 18.04
Hello good people

I recently got a server, for learning how to run a home server among other things. One of the things is that I'd like to run is a calibre server which serves my books to my reading devices. However, I'm finding myself unable to install Calibre in my vanilla Ubuntu Server 18.04 install.

This is the output of the installer script:

Code:

If I try to run either calibre or calibre-server I also run towards similar errors. I imagine it's a dependency issue, but I didn't see anything about the error messages that was calibre-related except a Debian bug ticket, and as far as I understand it the calibre install is supposed to be self-contained and discourages installing from repositories.
