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 at (BuiltinClassLoader.java:581) at (ClassLoaders.java:178) at (ClassLoader.java:522) at (Native Method) at (Class.java:398) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:52) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:34)

Can someone help?
