I must have done this a dozen times. I follow the instructions at http://help.github.com/mac-set-up-git/
Permission denied (publickey,keyboard-interactive). fatal: The remote end hung up unexpectedly
I have double checked a valid email which is the same email I use on github. I also have set my profile up properly using:
$ git config --global user.name "Firstname Lastname" $ git config --global user.email "firstname.lastname@example.org"
I also make sure that when I copy my key over that no newline or spaces are in the text.
I am pulling my hair on this one.
