IN SERVER MACHINE DO THE FOLLOWING AND CREATE REPO (ONE TIME)

$ sudo adduser git
$ su git
$ cd
$ mkdir .ssh

cd ~/.ssh
ls
# Lists the files in your .ssh directory

git@dipankar-OptiPlex-390:~/.ssh$ ssh-keygen -t rsa -C "dutta.dipankar08@gmail.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/git/.ssh/id_rsa): <Enter>
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/git/.ssh/id_rsa.
Your public key has been saved in /home/git/.ssh/id_rsa.pub.
The key fingerprint is:
68:b7:df:bc:78:15:84:e9:87:b2:da:75:26:b3:38:08 dutta.dipankar08@gmail.com
The key's randomart image is:
