What happened?

I tried to push to my repo and my Github Actions, which worked just fine last time, failed.

My GA workflow:

jobs:
  Build-Conda:
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        os: [macos-latest, ubuntu-latest, windows-latest]
    steps:

    - uses: conda-incubator/setup-miniconda@v2
      with:
        auto-update-conda: true
    - name: Build Conda Packages
      run: |
        conda install conda-build anaconda-client conda-verify
        conda config --set anaconda_upload no
        cd conda
        conda build .

Error: Process completed with exit code 1.

It seems that the cause is conda/conda#11364.

Using:

conda install conda=4.12.0 conda-build anaconda-client conda-verify

instead of

conda install conda-build anaconda-client conda-verify

fixes the problem.

@mxmlnkn This is a known issue and a duplicate of #4481 and will be addressed in the upcoming conda-build 3.21.9 release (see #4483).
