openVPN command line install instructions do not work for the final steps

I have installed OpenWRT on BPI-R3 several weeks ago and it works fine for cabled connections. I then installed PIA using OpenVPN on the router and the service doesn't start. The system log throws an error complaining about outdated encryption routines. So I decided to install an openvpn connection first and the last part of the current instructions (VPN Service) does nothing from the command line. I have type this in numerous times, it begins with umask go= and is followed by a number of lines that do nothing. It appears there is a bug in the first part of the instructions or a missing character or command. I'm a 50 year developer but this is my first time using this product or openwrt. Has anyone tested these instructions.

Thank You

It would be much easier to get help if there are details.

Which tutorial did you follow?
What version of OpenWrt are you using?
What errors were reported?
What is your config?

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
