How to install Azlux’s repository

Uh sorry but, why would I want this? you ask
I use it to keep my bpytop packages up to date, it also has other packages you could use it for.
Read more about it here: Personnal Azlux’s repository


echo "deb http://packages.azlux.fr/debian/ buster main" | sudo tee /etc/apt/sources.list.d/azlux.list
wget -qO - https://azlux.fr/repo.gpg.key | sudo apt-key add -

This is deprecated, I no longer use this repo.
