Solve the following python programming problem given the following code:
def publish(self, target_url, credentials = None, **extra) : 
    if (not locate_executable ('git')) : 
        self.fail ('git executable not found.
cannot deploy.') 
if ((target_url.host + '.github.io') == target_url.path.strip ('/')) : 
        branch = 'master' 
else : 
        branch = 'gh-pages' 
with _temporary_folder (self.env) as path : 
        ssh_command = None 
        def git(args, **kwargs) : 
            kwargs ['env'] = _patch_git_env (kwargs.pop ('env', None), ssh_command) 
            return Command ((['git'] + args), cwd = path, ** kwargs).proc () 
for line in git (['init']) : 
            (yield line) 
ssh_command = self.update_git_config (path, path, branch, credentials) 
        for line in git (['remote', 'update']) : 
            (yield line) 
if (git (['checkout', '-q', branch], silent = True).wait () != 0) : 
            git (['checkout', '-qb', branch], silent = True).wait () 
self.link_artifacts (path) 
        self.write_cname (path, target_url) 
        for line in git (['add', '-f', '--all', '.']) : 
            (yield line) 
for line in git (['commit', '-qm', 'Synchronized build']) : 
            (yield line) 
for line in git (['push', 'origin', branch]) : 
            (yield line) 

    
    

    Fix the buggy line: ssh_command = self.update_git_config (path, path, branch, credentials)

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

ssh_command = self.update_git_config (path, target_url, branch, credentials)
