We appear to be missing one or more essential library files in Ubuntu 20.04 on a [vps][1] machine rented from [contabo][2] running 8gb ram on 4 cores.

You will need to add them to your server before FML and Forge will run successfully.java.lang.ClassNotFoundException: net.minecraft.launchwrapper.Launch

Can someone help?
