To Reproduce Steps to reproduce the behavior:

With a YAML something like this:

name: Test

on: [push, pull_request]

jobs:
  build:
    runs-on: ${{ matrix.os }}
    strategy:
      fail-fast: false
      matrix:
        python-version: [pypy, pypy3]
        os: [
          ubuntu-20.04,
          ubuntu-18.04,
          ubuntu-16.04,
          macOS-latest,
          windows-latest,
        ]

    steps:
      - uses: actions/checkout@v2

      - name: Set up Python ${{ matrix.python-version }}
        uses: actions/setup-python@v2
        with:
          python-version: ${{ matrix.python-version }}

      - name: Test
        run: |
          python --version

Outputs something like:

Run python --version
Python 3.6.9 (d38cd66c14b8, Sep 23 2020, 08:01:17)
[PyPy 7.3.2 with GCC 7.3.1 20180303 (Red Hat 7.3.1-5)]

or:

Run python --version
Python 2.7.13 (6abe2e00c51d, Sep 23 2020, 05:06:33)
[PyPy 7.3.2 with GCC 7.3.1 20180303 (Red Hat 7.3.1-5)]

All images were updated and currently contains PyPy 7.3.3 so I am going to close this issue. The work that @konradpabjan mentioned will provide ability to install any version of PyPy on-flight to avoid delays with image updates in future.

We’ve started working on this. Some discussion have come up here: https://github.com/actions/setup-python/pull/161 but internally we’ve been planning on getting this done for much longer but we just haven’t had the bandwidth. (Keep your eyes out for Universe next week 😉 lots of exciting new things coming to Actions)

We’ll be knocking out different versions of PyPy + Nightly PyPy in one go. Expect this to land very very soon
