     default: Warning: Authentication failure. Retrying...  

SOLUTION

1. Press CTRL + Z to break the 'default: Warning: Authentication failure. Retrying... or wait for few more minutes

2. Login into your guest machine - vagrant ssh , which should prompt you for password, vagrant , the default password for vagrant

3. Then go to - /home/vagrant/.ssh  and remote all the contents inside it, if the path not existed create the directory - mkdir -p /home/vagrant/.ssh

4. Then run following commands

 wget --no-check-certificate https://raw.github.com/mitchellh/vagrant/master/keys/vagrant.pub -O /home/vagrant/.ssh/authorized_keys  
 chmod 0700 /home/vagrant/.ssh  
 chmod 0600 /home/vagrant/.ssh/authorized_keys  
 chown -R vagrant /home/vagrant/.ssh  

5. Exit from the gust machine and restart it ( vagrant reload)

6. Voila! Problem solved. You should be good to go.
