Can't connect to some OpenVPN providers using openvpn 2.5.0 and nm-openvpn plugin

[Esokrates]

There is a bug fixed upstream https://gitlab.gnome.org/GNOME/NetworkManager-openvpn/-/issues/64
This makes it impossible to use my VPN connections on Ubuntu 21.04. Please backport that fix before the release.

@Daniel Could you triage this to make it in before the release?

there is a similar other fix in https://gitlab.gnome.org/GNOME/NetworkManager-openvpn/-/commit/353a521b

I uploaded network-manager-openvpn 1.8.12-2ubuntu1 with the two commits mentioned above cherry-picked as patches.

I took some time to test this locally by setting up an openVPN server in a fully up-to-date hirsute VM (server, CA and client all in the same machine, don't do this at home!), with 'push "route-ipv6 ::/0"' added to the config (/etc/openvpn/server/server.conf).

With version 1.8.12-2, I get a "invalid IP6 config received" warning in the journal when attempting to connect to the VPN (and the connection fails), whereas with version 1.8.12-2ubuntu1 (built and installed from a PPA for testing purposes), I get "Data: No IPv6 configuration" (and the connection succeeds).

Thank you all for sorting this out quickly. I can confirm everything works fine now.
