YES
Removed my original answer to guide those to a better solution provided by @InfosecGreg (Thank you!) towards the bottom of this post.
If for some reason you are still struggling, the route I went is still an option, but as IG mentions, this is risky and tedious. Almost as tedious as being told to roll back my OpenVPN version by support staff.
Found it. This saved me SO MUCH TIME. Much more helpful than HTB Support.
You’re probably going to need to do what I did which was following some of the instructions at the bottom of the page linked above.
sudo -i
./configure
make
make install
openvpn --version
… will work.
I hope this helps!!!
Cheers!
