My Question or Issue

W: GPG error: http://repository.spotify.com stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7A3A762FAFD4A51F
E: The repository 'http://repository.spotify.com stable InRelease' is not signed.

I tried this but it does not work anymore, maybe because it is from 5 years ago. I'm running a fresh install of Linux and haven't messed with any repo configs.

Nevermind, it was solved using the following command. However, quite odd I had to add it if I installed Spotify using the Software store from mint.

curl -sS https://download.spotify.com/debian/pubkey_7A3A762FAFD4A51F.gpg | sudo gpg --dearmor --yes -o /etc/apt/trusted.gpg.d/spotify.gpg
