Unable to locate package openjdk-23-jdk & jre

[emptys0uL]

I encountered two errors while installing on Ubuntu. I installed JDK 23 and 21, but they’re not working. I think the reason loader.jar isn't being created is that the JDK is not installed correctly. But nothing works... Any solution?

I was having issues too, you need to be using JDK 23. I believe I installed it via snap and added this to my .bashrc after doing this it loaded properly:

export JAVA_HOME=/snap/openjdk/current/jdk
export PATH=$JAVA_HOME/bin:$PATH
