Почему cap deploy выдает Permission denied (publickey)?

Хорошо, я запутался в чем-то... Я могу сделать коммит в мой репозиторий github просто отлично, но когда я пытаюсь сделать cap deploy из моей локальной папки на мой staging сервер, я получаю Permission denied (publickey).

Если я запускаю ssh git@github.com, я получаю ошибку PTY allocation request failed on channel 0

Значит, что-то здесь не так.

Если я запущу ssh -vT git@github.com я получу:

Мои ключи находятся в папке ~/.ssh, так в чем проблема, и почему я могу зафиксировать репозиторий, если есть проблема с ключами??

UPDATE: Я заметил кое-что, когда зашел в свою папку .ssh. Там есть новая пара ключей, которая была создана при установке Github для Mac... почему она не могла просто использовать мою существующую пару ключей, я не знаю.
