unitySetup-2018.2.7f1 personal on Ubuntu 18.04 ERROR

Hi

I have installed unity 2018.2.7f1 personal on ubuntu 18.04 and when I launch any tutorial or try to create a new unity project I get the attached screenshot error?

Have you seen this before or have a solution for this?

Unity seems to fail at this point everytime

com.unity.package-manager-ui/Editor/Resources/Styles/Main_Dark.uss

Any help would be great
