Please share guide to install isaac ros on ubuntu 20.04

Hi @21coolkarni

Welcome to the Isaac ROS forum

If you are working with Isaac ROS on Orin NX, please update to Jetpack 6.0. The latest version of Isaac ROS 3.1 works with this release: Getting Started — isaac_ros_docs documentation

If you cannot update to Jetpack 6.0, follow the documentation related to Isaac ROS 2.1 that works with Jetpack 5.1.2 Getting Started — isaac_ros_docs documentation

Best,
Raffaello
