It finally worked! Thankyou so much. The installation was dodgy for me so I had to download JDK8 using: ~$ sudo apt install openjdk-8-jdk openjdk-8-jre Followed by: ~$ update-java-alternatives --config java Then select the java-8-openjdk-amd64/jre/bin/java from the list (to make java 8 the default, can switch and whatever but it works!!!) Thanks a tonne!

First of all thankyou so much for the quick response! So do I download and run Java 10? How do I downgrade it? Or should I uninstall it and reinstall Java 10? THanks again I've been working on this for hours

I'm running Minecraft on Java 11 (openjdk) and on Linux machine (Ubuntu) Vanilla works just fine, I downloaded the recommended forge 1.14.4 and installed it via the terminal without any issues. The game crashes after loading for a second. Not sure why? I downloaded the latest one after and it crashed too. Any help would be appreciated! No crash log folder for some reason but the latest log is as follows: [09Dec.2019 21:50:01.856] [main/INFO] [cpw.mods.modlauncher.Launcher/MODLAUNCHER]: ModLauncher running: args [--username,
