I am new to using Linux, and am trying to install the Sophos SSL VPN Client/Open VPN on a Google Compute Engine (GCE) running ubuntu-1604-xenial-v20210224. The instructions I have seen all refer to using the web browser to go and download the file containing the configuration, however GCEs don't have the gui installed, and I have tried several thing to install a simple gui to no avail. I imagine that there is a way to do all of this from the command line, but am not sure how.
Basically, I would like to install all of this from the command line, and then have the vm connect to the vpn on startup. Any help would be greatly appreciated.
