Issue with SSH key setup while setting up github

Question

I followed this tutorial to generate SSH key on github: At step number 5 of the above linked tutorial,after I type ssh -T [email protected] I am supposed to see this:

The authenticity of host 'github.com (207.97.227.239)' can't be established.
# RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
# Are you sure you want to continue connecting (yes/no)?

I, however, see this:

Agent admitted failure to sign using the key.
Permission denied (publickey).

Then later when I tried to push a file to repository using git push -u origin master, I get this:

Agent admitted failure to sign using the key.
Permission denied (publickey).
fatal: The remote end hung up unexpectedly

I think the problem is with the set up of SSH key. How can I get solve this problem?

I am using Linux.

might you have already checked it but, make sure your public key have full permission. or other thing you can do is delete the existing key and try regenerate it. — Nixit Patel
