You will need mongodb:

apt install mongodb-server

Mongodb isn't distributed by some later linux distributions, so you will need to download and install the MongoDB Community Server from mongodb.com.

No further database configuration is needed.

git clone https://gitea.mmmoxford.uk/dvolk/lo2
cd lo2
virtualenv env
source env/bin/activate
pip3 install -r requirements.txt
mkdir static

Now install yt-dl from https://github.com/yt-dlp/yt-dlp/releases/

rename the binary to youtube-dl and mark it as executable:

mv yt-dlp youtube-dl
chmod a+x youtube-dl

python3 lo2.py serve
