Done!
Also the keep in mind the feature you add should work on other systems too.

I had encountered the same issue in other parts of the code after fixing the located bug.

It is because we are using a different version of Ubuntu and therefore have other environment variables name.

The other problem there make this happened is I did not install any desktop environment which I am using ubuntu as Command line only.

Can I have your permission to wrap all the code with a try{} catch(){} function

making the following line as default output when cannot find argument
DE : No Desktop Environment Installed
CPU Temperature : cannot detect CPU temperature °C

There are another solution by using Linux command to find out information instead of finding the file path, but this required re-writing whole program, that's why I don't prefer doing this method

Sure!
Rather than giving default values you can print only the properties which are available on the system.
