Resolved the issue... you need to add the ssh public key to your github account.

1. Verify that the ssh keys have been setup correctly.
   1. Run ssh-keygen
   2. Enter the password (keep the default path - ~/.ssh/id_rsa)
2. Add the public key (~/.ssh/id_rsa.pub) to github account
3. Try git clone. It works!

Initial status (public key not added to git hub account)

foo@bn18-251:~$ rm -rf test
foo@bn18-251:~$ ls
foo@bn18-251:~$ git clone git@github.com:devendra-d-chavan/test.git
Cloning into 'test'...
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
foo@bn18-251:~$

Now, add the public key ~/.ssh/id_rsa.pub to the github account (I used cat ~/.ssh/id_rsa.pub)

foo@bn18-251:~$ ssh-keygen 
Generating public/private rsa key pair.
Enter file in which to save the key (/home/foo/.ssh/id_rsa): 
Created directory '/home/foo/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/foo/.ssh/id_rsa.
Your public key has been saved in /home/foo/.ssh/id_rsa.pub.
The key fingerprint is:
