Python server with web interface:
https://gitlab.com/RemixDev/deemix-webui
https://gitlab.com/RemixDev/deemix-gui/-/tree/main

Standalone GUI, Server or one-file Server for Linux/Win/Mac x86:
https://download.deemix.app/0:/

Note: all of the above require an arl = arl cookie after logging into (free) deezer account. i.e. F12 in Firefox, storage, cookies, arl, then copy the content. The cookie is valid for 3 months.
Entering the arl cookie in the web interface stores it per client. Storing it in ~/.config/deemix/.arl and using –serverwide-arl flag can use the same for all clients.

then
    echo "Backing up old version..."
    sudo rm -rf /opt/deemix-server-old
    sudo mv /opt/deemix-server /opt/deemix-server-old
