"You should have active Unity license" after installing for Linux

I have installed Unity for Linux form here https://forum.unity.com/threads/unity-on-linux-release-notes-and-known-issues.350256/page-2 and after that it asked me to run unity. I did this and a window appeared, that I should have an active Unity licence with two options. One option is "Quit" and another option brings me to main web page where no Linux version available.

What to do?

 

Try installing Unity Hub and launching it from there
