Expired Key Signature

[Primera]

Hello,

I am on Linux Mint, When I change repositories source to any european source I get this error from few days.

Do you get relevant output for the following?

apt-key list | grep "4773 BD5E 130D 1D45" -B3 -A2

Mine is

pub   rsa4096 2019-07-15 [SC] [expires: 2020-10-07]
      2EBF 997C 15BD A244 B6EB  F5D8 4773 BD5E 130D 1D45
uid           [ unknown] Spotify Public Repository Signing Key <tux@spotify.com>

If you don't have that key, download it and apt-key add it, as seen in https://www.spotify.com/is/download/linux/

Just to say thank you for pointing us in the right direction. Spotify has been working fine for over a year for me, but a while back I got the 'key cannot be verified' error so haven't been getting updates. All seems sorted after this:
curl -sS https://download.spotify.com/debian/pubkey.gpg | sudo apt-key add -
