Set up a local Calibre library

install calibre

works better on debian buster, than debian bullseye

get buster

sudo apt update
sudo apt install calibre

create library and add a book

The location of the directory will be in my home folder, which is /home/simoon.

mkdir calibre-library

wget http://www.gutenberg.org/ebooks/46.kindle.noimages -O christmascarol.mobi

Then, we use calibredb to add the book to our library

calibredb add *.mobi --with-library calibre-library/

You should get a message saying "1 book added".

Next, we're going to use calibre-server to start the service.

calibre-server calibre-library
