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.

pygit2==1.12.1 を使用する python:3.10 コンテナで traceback を再現し、その後 pygit2/remote.py の Remote.save 周辺と、同梱されている libgit2 バインディングを調べます。Remote.fetch がリポジトリの状態をどのように更新することを想定されているか、また文書化されたワークフローでこの欠落シンボルを回避できるかを確認します。報告された操作で AttributeError が発生しなくなり、その動作がテストでカバーされるか、明確に文書化されていれば完了です。
