Note that (at least for some projects) you must have a github account with an ssh key.

Look at the keys listed in your authentication agent (ssh-add -l)
(if you don't see any, add one of your existing keys with ssh-add /path/to/your/key (eg: ssh-add ~/.ssh/id_rsa))
(if you don't have any keys, first create one. See: http://rcsg-gsir.imsb-dsgi.nrc-cnrc.gc.ca/documents/internet/node31.html or just google ssh-keygen)

To verify that you have a key associated with your github account:

Go to: https://github.com/settings/ssh

You should see at least one key with a hash key matching one of the hashes you saw when you typed ssh-add -l just a minute ago.

If you don't, add one, then try again.
