How can I get the key signature from a GPG Public Key? For example, I need a signature for Spotify's public key here: https://download.spotify.com/debian/pubkey.gpg
Something like this, but for GPG Keys.
This is as far as I've got:
$ gpg pubkey.gpg
pub 4096R/130D1D45 2019-07-15 Spotify Public Repository Signing Key <tux@spotify.com>
Download the key, import it, extract the email and run gpg --fingerprint.
cd ~
curl -O https://download.spotify.com/debian/pubkey.gpg
gpg --import ~/pubkey.gpg
gpg --fingerprint tux@spotify.com
