I have a simple question for setting up DRIVE Xavier for the first time. I understand that a Host Machine is necessary. In the following video

NVIDIA DRIVE AGX Developer Kit - How to set up

In Minute 4.47 The instructor says he installed Ubuntu 16.04 5 for the Host
I have used other Nvidia products and they required Ubuntu 18 (18.04) for example. I tried once with my Ubuntu 20 machine and it was not possible

So my question is what is the requirement for the Host OS to initialize DRIVE Xavier for the first time?

Dear @kansai,
Please check Getting Started: DRIVE OS 5.2.6 :: DRIVE Platform Installation Guide with NVIDIA SDK Manager

One question. The Host also needs to have a Nvidia GPU , is that correct?

Yeah. For example, the below is the requirement for DriveWorks (from DriveWorks SDK Reference: Getting Started)
