The certificate for swupdate.openvpn.net expired on March 5, 2017.

This will be resolved soon.

I'm aware of this problem, and added --no-check-certificate to wget
GPG key was downloaded and installed, but apt show this warning.
Also i started get this error when certificate was valid (day before expiring)
