Cloning git repo causes error - Host key verification failed. fatal: The remote end hung up unexpectedly

The issue could be that Github isn't present in your ~/.ssh/known_hosts file.

Append GitHub to the list of authorized hosts:

ssh-keyscan -H github.com >> ~/.ssh/known_hosts

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)

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

Well, from sourceTree I couldn't resolve this issue but I created sshkey from bash and at least it works from git-bash.
