Solve the following python programming problem given the following code:
def ensure_repository(self, repo, path, owner = None, branch = None, sudo = True) : 
    "
        Makes sure the repository is create in the remote server.
        This method does not update the repository or perform any operations in it. It is merely used to ensure that the repository exists in the specified path.

        :param repo: Git repository url.
        :type repo: :class:`str`
        :param path: Path to create the local repository.
        :type path: :class:`str`
        :param owner: User that owns the repository directory. Defaults to :data:`None`, using the current one in the remote server.
        :type owner: :class:`str`
        :param branch: If specified, the given branch will be checked-out, otherwise it stays in the master branch.
        :type branch: :class:`str`
        :param sudo: If :data:`False`, won't sudo when creating the repository. Defaults to :data:`True`.
        :type sudo: :class:`bool`

        Example:
        ::

            from provy.core import Role
            from provy.more.debian import GitRole

            class MySampleRole(Role):
                def provision(self):
                    with self.using(GitRole) as role:
                        role.ensure_repository('git://github.com/python-provy/provy.git', '/home/user/provy',
                                               owner='user', branch='some-branch')
        " 
    self.__clone_repository (path, repo, owner, owner) 
    self.__checkout_branch (branch, path, repo, sudo, owner) 
    self.__normalize_ownership (owner, path) 

    
    

    Fix the buggy line: self.__clone_repository (path, repo, owner, owner)

#Here is Python program to fix the buggy line: self.
