Facing issue with Docker Build Mongo 4.4 Ubuntu 16.04

Hello All, I have the below Dockerfile for building Mongo. However it is failing to build every time and not sure what the problem is. As per existing articles, tried to remove sudo, https to http and some other stuff but nothing seems to work.

Could someone please help on this.
