Thanks to our government that is fighting with Telegram I can not access some Amazon/Google servers in US that I use in my work projects, so I had to set up Open VPN on one of my servers in Germany. Tried several bash scripts for VPN config, and here is the best one:

The script creates an *.ovpn file that you can then import into your Ubuntu connection manager and have a connection up and running in less than 10 minutes.
