ssh - Why does Fabric throw 'TypeError: argument must be an int, or have a fileno() method'? -

-

when running fabric task on remote server following stack trace:

[x.x.x.x] run: git fetch && git reset --hard origin/develop exception in thread thread-2: traceback (most recent call last):   file "/usr/lib/python2.6/threading.py", line 532, in __bootstrap_inner     self.run()   file "/var/lib/jenkins/jobs/deploy/workspace/.pyenv/lib/python2.6/site-packages/ssh/agent.py", line 115, in run     self._communicate()   file "/var/lib/jenkins/jobs/deploy/workspace/.pyenv/lib/python2.6/site-packages/ssh/agent.py", line 125, in _communicate     events = select([self._agent._conn, self.__inr], [], [], 0.5) typeerror: argument must int, or have fileno() method.

the fact fabric task trying perform git fetch , exceptions raised in ssh/agent.py makes me think wrong ssh authentication.

the same user can run git fetch outside of fabric, , task runs fine on laptop.

what's going on here? how resolve issue?

an issue raised on fabric's issue tracker mentions error might arise not having ssh-agent running on host.

i solved problem starting ssh-agent , adding user's key:

$> eval `ssh-agent` $> ssh-add ~/.ssh/id_rsa

success!
