--up script fails with '/etc/openvpn/update-systemd-resolved': No such file or directory (errno=2)

Since I reinstalled my ArchLinux distro I get an error when I want to use OpenVPN. Here is the full output:

quentin@QuentinDesktop ~/Documents> openvpn --config ulille-vpn.ovpn
2022-01-04 21:52:15 WARNING: Compression for receiving enabled. Compression has been used in the past to break encryption. Sent packets are not compressed unless "allow-compression yes" is also set.

Here is the truncated ulille-vpn.ovpn file content (I just truncated the CA certificates):

Note that I didn't write this one myself, it is given by my university to access its local network.

I already tried to install the openvpn-update-systemd-resolved AUR package and enable it on systemd but it changed nothing.

How can I fix it ?

Solution

Okay, after a quick looking at the configuration file (what I did not think before asking this question), I commented the last 4 lines of the chunk I posted, and it works !

I am sorry for asking this question, I though the config file my university distributes was valid but it looks like it is Fedora/Debian specific, which is kind of weird because it works perfectly fine without these four lines.

I hope this short lifespan topic can help someone else in a similar case ! :^)
