Thank you for your advice. I have installed Java 8u211 in its own folder on my Ubuntu 19.04 machine. I have clicked on the MultiMC "settings" button, chosen the "Java" topic, and navigated to the Java executable at "/usr/lib/jvm/java-8u211/jdk1.8.0_211/bin/java". I press the "Test" button, and it shows Success.
"Java test succeeded!
Platform reported: amd64
Java version reported: 1.8.0_211"
I then had to edit the instance file to match the new Java location. Launch seems okay so far!
Thank you very much.

Oh, so close! The MineCraft launch went all the way through and I was able to click on select a multiplayer server. I chose the proper server, that I have been using for weeks. Then I get this message:

Any further advice?
