Jetson Nano 4GB : Installation Error as per document guide

Jetson Nano 4gb kit - bought for learning emerging technologies, I followed installation process as per Nvidia guide line - installation and followed Nvidia video tutorial also. The reality is during the installation its throws error and patch not supported like … I kept in box. This is hard to say that its really wasted my times and ruined my intention also.

May I know how did you do the installation?
Which video tutorial you followed?
Are you having a host PC with Ubuntu OS 18.04?
