Hey folks!
This is a heads-up that there will be a new update to the Spotify Linux client signatures. The latest available client will not install this new key just yet, but it's coming soon.
Come February, you may see errors related to missing keys and failed signatures when trying to update Spotify if you haven't installed the new key. Note that it will be installed automatically starting with the upcoming client update.
Here is the updated key:
curl -sS https://download.spotify.com/debian/pubkey_5384CE82BA52C83A.asc | sudo gpg --dearmor --yes -o /etc/apt/trusted.gpg.d/spotify.gpg

Have a nice day!
