Fix For My Docker Install Issue

I haven't been able to install docker on my Ubuntu desktops until now because I kept getting an error. As a workaround, I would do all my builds in a virtual machine. However I now finally have the solution that worked for me.

Turn off your VPN before running the installer or starting the docker daemon.

This solution cane courtesy of codekoala from this github issue post. Thank you codekoala!
