Can't use the action on macos-12 executor

[ljmf00]

The new macos-12 executor is available as public beta for Github Actions. I'm experiencing issues setting up miniconda with this action.

Even though I didn't test it in an isolated environment, I believe this can be reproduced with the following workflow:

jobs:
  conda:
    runs-on: macos-12
    steps:
      - name: "Setup miniconda"
        uses: conda-incubator/setup-miniconda@v2
        with:
          auto-update-conda: true
          python-version: '3.7'
          auto-activate-base: true
          allow-softlinks: true

Hi @ljmf00 thanks for reporting the issue.

I'm experiencing issues setting up miniconda with

What seems to be the issue specifically? Could you point us to the failing run?

Cheers!

The macos-12 runners do not provide a bundled conda

https://github.com/actions/virtual-environments/blob/main/images/macos/macos-12-Readme.md
vs
https://github.com/actions/virtual-environments/blob/main/images/macos/macos-11-Readme.md

You could overcome this issue by specifying a miniconda-version or a miniforge version so that the action installs a new one instead of trying to find an inexistent one.

Ah ok, makes sense to me. I'll try and give some feedback here, if worth it 😊 . Feel free to close this if you don't track the upstream issue.

@ljmf00 it seems the new machines have been updated, so everything should be working fine. Rerunning the test PR I opened to check.

If everything runs we can close this :)

Ok everything is working now as expected. Thanks a lot for flagging this @ljmf00
