Alright! Hitch on and let's go on!

Pop!_OS 20.04

First, open the Pop!_Shop.

Next, type "Minecraft" into the search bar, and click "Minecraft".

Next, click install.

Now you will have installed Minecraft! Open Minecraft and log in with your username and password to start playing!

Debian and Ubuntu

  First, you will need Java runtime.

sudo apt-get install openjdk-8-jre

So, you want oracle runtime instead? But.... fine....
Get the repository and install the package.

sudo apt-add-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

You will then download the launcher. Go to the minecraft.net page to download or...

wget http://s3.amazonaws.com/Minecraft.Download/launcher/Minecraft.jar

Now run the file! Log in with your username and password and start playing!
