  • apt uses GPG to verify cryptographic signatures on packages that it downloads, to prevent tampering. The error sounds like you are missing key 73F0D6E88E3D6C3A from the keyring. I don't know how to manually update the keyring list though. – rlee827 May 31 '17 at 02:49

You should add "playonlinux" repository's public key:

wget -q "http://deb.playonlinux.com/public.gpg" -O- | sudo apt-key add -

after that run :

sudo apt update

from playonlinux download page.
