_pygit2.GitError: authentication required but no callback set

I'm guessing this is an issue on my end, not really an issue with pygit2, but I've been stuck on it for two days with almost no progress and the documentation isn't making sense to me.

I am trying to push to a repository using user name and password credentials and getting the error:

File "createRepo.py", line 72, in remote.push(['refs/heads/master']) File "/usr/local/lib/python2.7/dist-packages/pygit2/remote.py", line 470, in push check_error(err) File "/usr/local/lib/python2.7/dist-packages/pygit2/errors.py", line 64, in check_error raise GitError(message) _pygit2.GitError: authentication required but no callback set

```
#Clone the newly created repo
repoClone = pygit2.clone_repository(repo.git_url, '/var/www/html/uploads/tmp')
print "GIT URL: "
print repo.clone_url
print "<---"

#Add the new files to the repo
for file in files:
    os.rename("/var/www/html/uploads/" + file, "/var/www/html/uploads/tmp/" + file)

#Commit it
repoClone.remotes.set_url("origin", repo.clone_url)
index = repoClone.index
index.add_all()
index.write()
author = pygit2.Signature("MaslowCommunityGardenRobot", "info@maslowcnc.com")
commiter = pygit2.Signature("MaslowCommunityGardenRobot", "info@maslowcnc.com")
tree = index.write_tree()
oid = repoClone.create_commit('refs/heads/master', author, commiter, "init commit",tree,[repoClone.head.get_object().hex])
remote = repoClone.remotes["origin"]
credentials = pygit2.UserPass(userName, password)
remote.credentials = credentials
remote.push(['refs/heads/master'])

The documentation clearly says that there is an optional callback argument push(specs, callbacks=None), but how and when to use that feature is not clear.

If I can get this to work I will post it as a clear, simple example of how to create a repository with pyGitHub, clone it, create a commit, and push it which is something I think is missing.

Comienza con createRepo.py alrededor de la línea 72 y la documentación de pygit2 remote.push(specs, callbacks=None); después compara la asignación de UserPass con la API de callbacks. Determina si falta la guía o el ejemplo de autenticación, y considera que el issue está terminado cuando el flujo de autenticación de push requerido esté claramente documentado o demostrado.
