Hello,

i want to install a spotify client.


pfiff@netrunner-pfiff:~$ echo deb http://repository.spotify.com stable non-free | sudo tee /etc/apt/sources.list.d/spotify.list 
[sudo] Passwort für pfiff: 
deb http://repository.spotify.com stable non-free
pfiff@netrunner-pfiff:~$ sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com BBEBDCB318AD50EC6865090613B00F1FD2C19886  
Executing: /tmp/apt-key-gpghome.1yS1xVZWKA/gpg.1.sh --recv-keys --keyserver keyserver.ubuntu.com BBEBDCB318AD50EC6865090613B00F1FD2C19886
key 13B00F1FD2C19886:
3 Beglaubigungen wegen fehlender Schlüssel nicht geprüft
gpg: Schlüssel 13B00F1FD2C19886: Öffentlicher Schlüssel "Spotify Public Repository Signing Key <operations@spotify.com>" importiert
gpg: Anzahl insgesamt bearbeiteter Schlüssel: 1
gpg:                              importiert: 1

but got this answer. How can I activate this repository despite the missing key? Or, how can i get the key?

Ciao!

Dieter

Looks to me like it imported the key just fine.
Is it spilling out any error message for that specific repository when running sudo apt update?

I’m not sitting at this specific pc to quote the messages correctly but there is a error message concerning this repositpory during sudo apt update. (Refusing the repository because of missing key …)

Ciao!
