   Similar but slightly different message in our system, when calling

   REPO = Repo(ARGS.repositoryPath)
   REPO.submodule_update(recursive=True)
   

   File "C:\Program Files\Python36\lib\site-packages\git\repo\base.py", line 353, in submodule_update
       return RootModule(self).update(*args, **kwargs)
     File "C:\Program Files\Python36\lib\site-packages\git\objects\submodule\root.py", line 339, in update
       keep_going=keep_going)

       raise GitCommandError(self.args, status, errstr)
   git.exc.GitCommandError: Cmd('git') failed due to: exit code(128)
     cmdline: git fetch --progress -v __new_origin__

   We are on a Gitlab instance where relative submodule URLs are a must have:

   If you are using GitLab 8.12+ and your submodule is on the same GitLab server, you must update your .gitmodules file to use relative URLs

   I was able to workaround this issue by manually resolving the relative path in the .gitmodules file. If you care about the .gitmodules file retaining the relative path url, you could easily just set the original url back to the .gitmodules file after operating on the repo with gitpython.

   for submodule in repo.submodules:
   
       # Hack around gitpython bug: https://github.com/gitpython-developers/GitPython/issues/730
       if submodule.url.startswith('..'):
           submodule_repo_name = submodule.url[3:]  # Strip off '../'
           repo_parent_url, _ = os.path.split(origin.url)
           actual_url = os.path.join(repo_parent_url, submodule_repo_name)
           with submodule.config_writer() as writer:
               writer.set('url', actual_url)
   
       print(f'Processing submodule {submodule.name}')
       submodule.update(init=True)

   Another workaround I'm currently using is to use git directly as described in https://gitpython.readthedocs.io/en/stable/tutorial.html#using-git-directly

   for sm in repo.submodules:
         # Calling git directly for own submodules since using relative path is not working in gitpython
         # see https://github.com/gitpython-developers/GitPython/issues/730
         if sm.url[0:3] == '../':
             repo.git.submodule('init', sm.name)
             repo.git.submodule('update', sm.name)
         # For external submodules we can use the update function of gitpython
         else:
             sm.update()
