AttributeError: cffi library 'pygit2._libgit2' has no function, constant or global variable named 'git_remote_save'

I've installed using pip install pygit2==1.12.1. The environment is a python:3.10 docker container.

I'm receiving:

Traceback (most recent call last):
  ...
  File "...", line 197, in pull_repo
    remote.save()
  File "/app/env/lib/python3.10/site-packages/pygit2/remote.py", line 117, in save
    err = C.git_remote_save(self._remote)
AttributeError: cffi library 'pygit2._libgit2' has no function, constant or global variable named 'git_remote_save'. Did you mean: 'git_remote_name'?

The relevant code associated with this error is as follows:

repo = pygit2.Repository(checkout_location)
remote = repo.remotes['origin']
remote.fetch(callbacks=callbacks)
remote.save()

I attempted to use the Remote.save method because the call to Remote.fetch didn't appear to do anything to the repository, which is known to have changed.

Note, I could be using this all wrong, but I would still think an AttributeError shouldn't be raised. Also, there isn't a good example or clear way to do the equivalent of a git pull, which is why I'm fiddling with fetching the remote in order to advance the index.

Reproduce el traceback en el contenedor python:3.10 con pygit2==1.12.1 y, después, inspecciona pygit2/remote.py alrededor de Remote.save y los bindings de libgit2 incluidos. Comprueba cómo se espera que Remote.fetch actualice el estado del repositorio y si el flujo de trabajo documentado evita este símbolo ausente; la tarea estará terminada cuando la operación indicada ya no genere AttributeError y su comportamiento esté cubierto o claramente documentado.
