Install root 6.22 on ubuntu 20.04

Good!

  1. yes, some resources here and here (but it should not be that much different than an installation on actual ubuntu, besides maybe the fact you need Xming as an X11 server)

  2. there is experimental support, see e.g. the 6.22 release page – we test ROOT on windows and a large part of the features work. It would be great if you could open another forum topic about the difficulties you had with windows

Cheers,
