OpenVPN3 installation problem

luchoaraya30

I'm trying to install OpenVpn3 on Ubuntu 18.04 following the official guide (https://community.openvpn.net/openvpn/wiki/OpenVPN3Linux), but can't install the repository key ($ wget https://swupdate.openvpn.net/repos/openvpn-repo-pkg-key.pub), I get the following error:

https://swupdate.openvpn.net/repos/openvpn-repo-pkg-key.pub

To connect to swupdate.openvpn.net insecurely, use `--no-check-certificate'.

Adding the --no-check-certificate flag throws the following error:

Any idea on what should I do?
