I’m trying to install openvpn to my droplets .
I have successfully installed both openvpn and easy-rsa

apt-get  install openvpn easy-rsa

But when it comes to editing the server.conf file, that’s where I get stuck.
Once I run this command to open the server.conf with Vim editor:

vim /etc/openvpn/server.conf

I’m getting a black screen with blue ‘dashes’ (-) all the way to the bottom
and
E35: NO previous regular expression.

Kindly let me know where I’m going wrong.

Note: The problem started when I entered an SSH key on a different droplet.
