Issue

In a clean environment, when update to pluggy 1.1.0:

  Package   Version  Build         Channel         Size
─────────────────────────────────────────────────────────
  Upgrade:
─────────────────────────────────────────────────────────

  - pluggy    1.0.0  pyhd8ed1ab_5  conda-forge
  + pluggy    1.1.0  pyhd8ed1ab_0  conda-forge     21kB

It makes conda unusable in a Mac Apple M2:

Hey, thanks for reporting this.

Would mind reporting this upstream?

Actually I think this might have been already reported: https://github.com/pytest-dev/pluggy/issues/403

Closing this issue as it does not seem related to the conda package.

[nicoddemus]

Actually let's keep this open, as others with the same problem might land here.

I will pin this issue, but the package has been yanked: https://github.com/conda-forge/admin-requests/pull/737
