I'm running Debian GNU/Linux 11 (bullseye).

I'm trying to install the Tizonia cloud music player for the terminal. I ran the command:

```
curl -kL https://github.com/tizonia/tizonia-openmax-il/raw/master/tools/install.sh | bash

```

But I end up getting the following error:

```
E: Unable to locate package libspotify12

```

This stalls the installation, and also makes it impossible to clean up my mess using this command:

```
sudo apt-get -y remove --purge tizonia-all && sudo apt-get -y autoremove

```

Because Tizonia never ends up getting installed:

```
E: Unable to locate package tizonia-all

```

What source should I add to my Debian APT sources list to get access to `libspotify12`, in order for the installation to proceed normally?
