Google didn't provide much help finding an answer to this.
I get this message:
$ sudo apt-get update
Err:10
https://build.openvpn.net/debian/openvpn/stable xenial Release.gpg
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8E6DA8B4E158C569
I'm unable to locate an update for this key, what should I do?
Thanks, CJ
