I have looked and I cannot find any clear instructions for installing Ignition 8.05 Edge on Ubuntu Linux 18.04 LTS. Does that exist? I am happy to be corrected (and hang my head in shame) if I have just overlooked it somewhere [Update: I have corrected myself, see next post].
Current Ignition version as of writing this is 8.05.20191015-1642.
There is a .run executable available from the Ignition downloads page, that file works only for installing the non-Edge Ignition edition.
The ignition University video for ‘installing-ignition-on-linux’ uses the the 8.0.0-beta version of the the .run executable and that shows the installation prompting for the choice of Platform Edition, Ignition or Ignition Edge. However in the current 8.05 version of the .run executable the Platform Edition prompt is not presented.

A search of the forums indicates that the removal of Edge from the .run executable was intentional and that “Edge will only be distributed via the zip bundles and not the installers”.
Installer no longer supports
–edition flag for Edge vs Full?
So it would appear that, for reasons unknown, the .zip bundle is the way to install Ignition Edge on Linux but no real guidance on how to do that properly is provided (that I could find).
I did find a knowledge base article for 'Installing Ignition Edge of Rasberry Pi", however that is based on v7.9.2. I was able to use that as a reference to get things working on Ubuntu to the point where I can access the Gateway webpage and connect with the Designer. But there are a number of steps in these instructions that are not correct for v8.x (Installing Oracle Java, list of files to make executable, etc.) I took by best guess but am worried that I overlooked something.

So, is there any official (or non-official) documentation of how to configure Ignition Edge 8.x correctly in Ubuntu Linux?
Decides to do a double check before posting, finds answer, decides to post anyway for the edification of others who may have the same questions. Will update answer in next post.
