  Installing Forge for Minecraft on Ubuntu 20.04

  Posted by profmag on March 13, 2021 at 2:18 am

  For Ubuntu 20.04 we’ve been using the mc-installer snap from the Ubuntu Software Center app to install Minecraft. Since this is a snap, it doesn’t install java in a place accessible to the rest of Ubuntu. This means we can execute self-extracting java jars. One of these is the Forge moding engine. Clicking it to install results in an attempt to open the jar in a text editor for editing.

  To solve this, we need to install Java SE JDK or open JDK, usually version 11.

  To do this:

  1. Open Ubuntu Software Center and search for “Synaptic Package Manager”. Synaptic is a great GUI for viewing and installing packages.
  2. After installing Synaptic, open it and click the “Search” button on the top right.
  3. Search for “jdk” and install the open jdk package recommended for your setup. To install, click the checkbox next to the package and “Mark for installation”.
  4. A message window will pop up and list all the associated packagers to be installed. Click “Mark” to go ahead.

  The packages will now install. You can try “java -version” in a terminal to confirm the install and see your version. Now you should be able to install jar files.
