Unit raspotify.service could not be found.

[HenrikSx]

Hey,
I tryed to install Raspotify. At first with the wrong routine. Tried to make it undo ant tried the right routine.
My first try:

curl -sSL https://dtcooper.github.io/raspotify/key.asc | sudo apt-key add -v -
echo 'deb https://dtcooper.github.io/raspotify raspotify main' | sudo tee /etc/apt/sources.list.d/raspotify.list

Try to make it undo:

sudo apt purge -y raspotify    
sudo rm -f /etc/apt/sources.list.d/raspotify.list
sudo rm -f /user/share/keyrings/raspotify_key.asc
curl -sSL https://dtcooper.github.io/raspotify/key.asc | sudo apt-key del

Then to tried:

 sudo apt-get -y install curl && curl -sL https//dtcooper.github.io/raspotify/install.sh | sh

The result was:

Paketlisten werden gelesen... Fertig
Abhängigkeitsbaum wird aufgebaut.
Statusinformationen werden eingelesen.... Fertig
curl ist schon die neueste Version (7.64.0-4+deb10u8).
0 aktualisiert, 0 neu installiert, 0 zu entfernen und 1 nicht aktualisiert.

But it doesn't work:

pi@raspberrypi:~ $ sudo systemctl status raspotify                              Unit raspotify.service could not be found.

Maybe you can help me.... I tried to find simular problems.... not sure, but couldn't find something help me
