Does anyone know what they're doing with Unity 3D?

Above.

I've been trying to do Unity tutorial projects all week, and the projects just do NOT work, I'm using version 2021.3.3 on Ubuntu Linux, allegedly a supported operating system.

I've asked on the official Unity forum but nobody's willing to help me.

Do something before I unplug and throw this PC in t'bin.
