I will research this issue more I swear when I get 30 minutes to myself, but wanted to make a topic in case it is a bug that needs to be fixed.
I just upgraded to PopOS 22.04. GanttProject won’t launch. Here is my terminal output
┬─[richard@pop-os:~]─[06:22:34 AM]
╰─>$ ganttproject

You may want to set the path to the root of your Java Runtime installation
in JAVA_HOME environment variable or pass it to ganttproject in --java-home argument
Maybe an issue with the installed version of OpenJDK after the upgrade? Here is what I have installed.

I’ve tried removing GanttProject and re-installing. I haven’t tried removing openjdk and reinstalling yet. Like I said, I’m interested in researching this issue when I have more time later.
