Unity2020.3.* doesn't works on Linux

I tried Unity-2020.3.36, 2020.3.38, 2020.3.39 on ArchLinux.
All of them doesn’t work for me.

Reproduce:

  1. Open UnithHub then install Unity-2020.3.xx ( it’s 2020.3.39f1 now).
  2. Click [New Project]-[Learning]-[2D Platformer Microgame]-[Create project]
  3. Then it open the project and show me two empty errors in Console UI.

I’m having the same issue. Tried on fedora 37 and 38 and on Ubuntu 23.04, none of them worked

2020.3 editor is no longer supported for a while. Please do upgrade to the latest LTS version

I managed to get the most recent 2021 version to work a few months back.

Although to be honest, I’ve pretty much given up on Unity in general and have migrated to Godot Game Engine.

I use unity 2020.3 on Linux all the time and it works just fine. 2021.3 works fine too.

Unity works great on Linux, been using it for work for many years on a daily basis!

I got the same error too. but you can check the Editor.log:

-----CompilerOutput:-stderr----------
No usable version of the libssl was found
/home/eyap/Unity/Hub/Editor/2020.3.33f1/Editor/Data/Tools/RoslynScripts/unity_csc.sh: line 3: 25959 Aborted (core dumped) "/home/eyap/Unity/Hub/Editor/2020.3.33f1/Editor/Data/Tools/RoslynScripts/../../Tools/Roslyn/csc" /shared /noconfig @temp/UnityTempFi
-----EndCompilerOutput---------------

“No usable version of the libssl was found” means you didn’t have libssl to use.you can use the follow bash code to install a libssl

echo "deb http://security.ubuntu.com/ubuntu focal-security main" | sudo tee /etc/apt/sources.list.d/focal-security.list
sudo apt-get update
sudo apt-get install libssl1.1

it’s works for me! you can try it

Thanks so much. After two days of searching, your’s was the most direct and simplest solution

I can’t run those version on Ubuntu 23.10 or Fedora 39 which forced me to use Ubuntu 22.04:face_with_spiral_eyes:
