Together with your server initialized, your first step is to install Java; you’ll need it to run Minecraft.
Replace the package index for the APT bundle supervisor:
sudo apt replace
Subsequent, install the OpenJDK version sixteen of Java, specifically the headless JRE. It is a minimal version of Java that removes the support for GUI functions. This makes it ideal for working Java applications on a server:
