manually install unity version in linux fedora

I was having the https://stackoverflow.com/questions/66492234/unable-install-unity-version. I thought it would be better if I install unity version manually. I found twice https://docs.unity3d.com/2021.1/Documentation/Manual/InstallingUnity.html https://unity3d.com/get-unity/download/archive. I noticed that there's nothing for Linux. Where will I get installation file for Linux? I found some code to run in terminal `sudo installer [-dumplog] -package Unity.pkg -target /` `sudo installer [-dumplog] -package StandardAssets.pkg -target /` `sudo installer [-dumplog] -package Examples.pkg -target /`. But, I am unable to understand them cause, I am new to Linux. I tried it also `sudo dnf install mesa-libGLU`. I got a message Package mesa-libGLU-9.0.1-3.fc33.x86_64 is already installed. Dependencies resolved. Nothing to do. Complete!. What to do next?

 

We recommend using the Hub for Linux. The Hub button in the download archive will work if you have it installed and have followed the steps in this pinned thread.

 

I am on Ubuntu 20.04. The Unity Hub works best for me.

Best,
