The CI is failing for Ubuntu with all versions (except PyPy). For example:

ERROR Tests/test_image_fromqimage.py::test_sanity_1 - Failed: fixture function has more than one 'yield':

    @pytest.fixture
    def test_images() -> Generator[Image.Image, None, None]:
        ims = [
            hopper(),
            Image.open("Tests/images/transparent.png"),
            Image.open("Tests/images/7x13.png"),
        ]
        try:
            yield from ims
        finally:
            for im in ims:
                im.close()
