hg pull from bitbucket using fabric

I'm trying to use fabric to deploy a Django project and I get this error when I run hg pull:

[myusername.webfactional.com] run: hg pull
[myusername.webfactional.com] out: remote: Warning: Permanently added the RSA host key for IP address '207.223.240.181' to the list of known hosts.
[myusername.webfactional.com] out: remote: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
[myusername.webfactional.com] err: abort: no suitable response from remote hg!

Fatal error: run() encountered an error (return code 255) while executing 'hg pull'

I can run other mercurial commands like hg status, and hg log just fine from my fab file.

I have generated an SSH key on the server and added it to my bitbucket account. This works as I can SSH in and run hg pull and it works fine, it's only when using fabric.

This is my fabfile:

from __future__ import with_statement
from fabric.api开发者_开发知识库 import *

env.hosts = ['myusername.webfactional.com']
env.user = "myusername"

def development():

    # Update files
    local("hg push")
    with cd("~/webapps/mysite/mysite"):
        run("hg pull")

    # Update database
    with cd("~/webapps/mysite/mysite"):
        run("python2.6 manage.py syncdb")
        run("python2.6 manage.py migrate")

    # Reload apache
    run("~/webapps/mysite/apache2/bin/restart")

Any ideas?

EDIT:

Got this working using https

so instead of

hg pull

I'm using

hg pull https://myusername@bitbucket.org/myusername/mysite

Can't reproduce.

zada$ fab development
[ostars.com] Executing task 'development'
[ostars.com] run: hg pull
[ostars.com] out: pulling from ssh://hg@bitbucket.org/Zada/b
[ostars.com] out: no changes found

Done.
Disconnecting from ostars.com... done.

zada$ hg --version
Mercurial Distributed SCM (version 1.6.3)
zada$ ssh ostars.com "hg --version"
Mercurial Distributed SCM (version 1.6)
zada$ fab --version
Fabric 0.9.2

Possible reasons: versions mismatch. Or just a glitches on Butbucket :) Try run("hg pull") to be more verbose.

To use SSH to clone or pull or push repository in BitBucket you need to follow this instruction (this document is for Mercurial on Mac OSX or Linux) :

If you want to setup other ssh to to work with bitbucket, here is the full documentation :
