Method of installing ROS Noetic in Ubuntu20.04

Affirmation: Because the project needs to use ros environment, So here, record the installation process of ROS Noetic under ubuntu 20.04 under 1. The whole process is successfully installed once in sequence. Of course, when the next step is executed, the last step must be successfully executed. When the network is not good, you can try it several times. The following is the process I personally practiced. Now I share it with you for an exchange and study. This process refers to the official installation steps. Here is the official link http://wiki.ros.org/noetic/Installation/Ubuntu.
