                Switching to nearest mirror using terminal in ubuntu server with "mirror" method.
              
          
    The apt mirror method

A gem was found during my google search. Not much known as it said(at least during this writing),but works damn good.
This mirror method will automatically select the fastset mirror during apt update. based on your location.
tested and running well on Ubuntu Server 18.04

First, open /etc/apt/sources.list with a text editor.


sudo nano /etc/apt/sources.list

                How to contribute to a project on Github
              
          
    This text now lives at https://github.com/MarcDiethelm/contributing/blob/master/README.md.
I turned it into a Github repo so you can, you know, contribute to it by making pull requests.

Contributing

If you want to contribute to a project and make it better, your help is very welcome. Contributing is also a great way to learn more about social coding on Github, new technologies and and their ecosystems and how to make constructive, helpful bug reports, feature requests and the noblest of all contributions: a good, clean pull request.
