Perfect. I got the Forge version to run by manually switching my Java version to 8 with the updates-alternative configuration tool earlier this morning, but very much prefer the option diesieben07 gave in his answer. Problem solved. Thanks a lot!

Thanks for this answer. Since I need Java 11 for other purposes on my computer, is there a way to tell Minecraft which Java version to use? The launcher seems to have this option, but I don't know what to put in the field for the java executable. Currently I have Java 8 and Java 11 installed as follows: java-1.11.0-openjdk-amd64 1111 /usr/lib/jvm/java-1.11.0-openjdk-amd64 java-1.8.0-openjdk-amd64 1081 /usr/lib/jvm/java-1.8.0-openjdk-amd64 Specifying the path /usr/lib/jvm/java-1.8.0-openjdk-amd64 in the launcher field for the forge installation produces a rather confusing error message: Unable lo locate the Java runtime Error details: Success Filename on disk: java-8-openjdk-amd64 Path: /usr/lib/jvm/java-8-openjdk-amd64 Exists: Directory Also, the vanilla versions of Minecraft seem to work perfectly fine with the Java 11 (it is just the Forge versions that produce the error).

After not playing Minecraft (Java Edition on Ubuntu 18.04 64bit) for a year I just installed the new launcher which works fine in vanilla starting up versions 1.14.4 and 1.13.2 without any problems. Then I installed Forge 1.13.2-forge.25.0.219 as well as Forge 1.14.4-28.1.0, but with both options the launcher crashes with Error Game crashed An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience. Any idea how to fix this? Thanks in advance. debug.log latest.log
