Broken SSL in MacOS CI

[crusaderky]

As of this morning, all test suites fail on MacOS github actions, e.g.

https://github.com/dask/distributed/runs/4534704460?check_suite_focus=true

______________ ERROR collecting distributed/comm/tests/test_ws.py ______________

The cryptography package hasn't been updated recently.

Can anybody with a Intel mac laptop try to reproduce?

Thanks for surfacing @crusaderky. I was able to reproduce on my Intel mac using the environment file in the mamba export step of that CI build.

FWIW I've seen similar Reason: image not found failures popping up in other projects too. For example over in https://github.com/dask/dask/pull/8472 we're getting (see this CI build):

py.test dask --runslow --cov=dask --cov-report=xml -n4 
ImportError while loading conftest '/Users/runner/work/dask/dask/conftest.py'.

and in https://github.com/coiled/dask-bigquery/pull/31 (see this CI build):
