I use Pop! OS and not sure really how to run the tools as necessary.
Since, Pop! OS is is based on Ubuntu so I presume it's the same. All I can find are directions based off of Ubuntu LTS 16 or the most recent Linux system being Linux Mint 19.... I tried giving permissions to execute but still doesn't run, tried to run chmod command but says 'PATH doesn't exist.' I installed Java months back but still not sure what to do in that regard.
This means that you are not issuing the commands in the correct directory. You can check your current directory by typing the command
I would suggest that you read or watch a short tutorial of how to use the command line if you are not familiar with it. You don't need any advanced stuff, but you will need the basics later to run things like the provided Jack compiler.
Another common pitfall under Linux is, that people install the so called "headless" openjdk package. "Headless" in this case means that it does not have any GUI capabilities, which is what people want to run on the server. To make sure you have the correct JDK, you can issue the following command:
I put the JDK command and this is the result: sudo apt install openjdk-11-jdk

openjdk-11-jdk is already the newest version (188.8.131.52+1-0ubuntu1~20.04).
openjdk-11-jdk set to manually installed.

I presume I should upgrade ? I installed the package, ensured permissions was set.
