Describe issue

Sphinx build fails at "make html" from the workflow below. It seems to be a timezone related issue that arises from the interaction of the Python packages babel & zoneinfo.

It is important to mention again, that it runs fine when pushing to Github, but unfortunately not in act.

Find the error below:

@liopeer I ran into this issue today. There's definitely a problem with how the timezone is being retrieved by babel, but you can get around it by setting TZ=UTC to short circuit the problem during the sphinx build:

name: "Push Docs Build"
on: [push]
permissions:
  contents: write

jobs:
  # anything in the job "docs" is executed on the same runner
  docs:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Build docs
        run: |
          wget https://bootstrap.pypa.io/get-pip.py
          python get-pip.py
          cd $GITHUB_WORKSPACE/docs
          python -m pip install -r requirements.txt
          TZ=UTC make html
      - uses: peaceiris/actions-gh-pages@v3
        if: ${{ github.event_name == 'push' && github.ref == 'refs/heads/main' }}
        with:
          publish_branch: gh-pages
          github_token: ${{ secrets.GITHUB_TOKEN }}
          publish_dir: docs/build/html/
