Unable to ssh push in pygit2

    Push the given refspec to the remote. Raises ``GitError`` on protocol
    error or unpack failure.

    When the remote has a githook installed, that denies the reference this
    function will return successfully. Thus it is strongly recommended to
    install a callback, that implements
    :py:meth:`RemoteCallbacks.push_update_reference` and check the passed
    parameters for successfull operations.

    Parameters:

    specs : [str]
        Push refspecs to use.

    proxy : None or True or str
        Proxy configuration. Can be one of:

        * `None` (the default) to disable proxy usage
        * `True` to enable automatic proxy detection
        * an url to a proxy (`http://proxy.example.org:3128/`)

El traceback apunta a pygit2/remote.py en Remote.push, donde se llama a payload.check_error(err). Reproduce el fallo del push mediante SSH e inspecciona la firma de check_error y el flujo de push circundante; se considera terminado cuando el push mediante SSH ya no lanza este TypeError.
