The "answer" I posted was more appropriate as a comment. Reposted for informational purposes.

I suggested

xhost +SI:localuser:root

John replied:

"xhost does not help. xeyes works as root. DISPLAY is set and X11 is working without issue."

It sounds like you're trying to install as root?

If so, can you install it as a local user with sudo instead? It doesn't appear the GUI is designed to work as root.

If not, perhaps this post will be helpful:

I've tried as root and non-root, both fail.

But the install matrix shows aht support for Ubuntu 16.04 has been dropped? And that is the platform that I am using.

I guess that's your answer, then. There's already not a ton of support or expertise available for linux installs. I wouldn't know how to troubleshoot it, other than upgrade one, or downgrade the other
