[SOLVED] OpenVPN client issue: "no resolvconf in ((null))"

Hi all,

I'm trying to connect to a third-party VPN provider using the keys, certificate and configuration files they provided. Here's the ouput from sudo openvpn --config mullvad_linux.conf It's the third line from the bottom that's giving me problems.

/usr/share/openvpn/update-resolv-conf contains the exact contents the Arch Wiki gives for it and is executable.
Any ideas on how to resolve this? There seems to be a discussion of the exact same problem here but it's in German and what I understand from Google Translate is that they didn't find a solution.

Re: [SOLVED] OpenVPN client issue: "no resolvconf in ((null))"

Have you tried it without that update-resolv-conf?

Otherwise try this in update-resolv-conf

## You might need to set the path manually here, i.e.
RESOLVCONF=/usr/bin/resolvconf
#RESOLVCONF=$(which resolvconf)

I tried your second suggestion first and that solved it, thanks!
