Pip: Temporary Failure in Name Resolution

[learnitall]

Hello! I have a question/concern about a recent CI run for our repo (can be found at https://results.pre-commit.ci/run/github/190794759/1629904875.ZfPbKKAGSqO4ZowEPRq5wQ). We're using the mypy hook and have enabled typing stubs to be automatically downloaded via pip, however we had the following errors crop up during the hook execution:

mypy.....................................................................Failed
- hook id: mypy
- exit code: 1

Installing missing stub packages:
/pc/clone/YrazQxi0S1yH44hGHdKFJg/py_env-python3/bin/python -m pip install types-PyYAML types-python-dateutil types-redis types-requests types-setuptools

From my perspective this seems to be an issue within the pre-commit CI environment because I can successfully do a fresh pre-commit run on my local dev machine:

Is this a temporary error within the CI? Or is there something on our end that we need to do? We've been using pre-commit CI for a couple weeks now and this is the first time an issue like this has cropped up. If this would be more appropriate to raise within the mypy hook repo, then let me know and I can move this over there.

Thanks!

note that you're using mypy in an unsupported configuration: https://github.com/pre-commit/mirrors-mypy/issues/50#issuecomment-859261537

Ah I see, thank you!

I appreciate your help- my apologies for not doing my research before raising an issue. I'll be more diligent next time.
