No module named pip for x86 manylinux_2_28

[jennydaman]

My actions contains a section like:

  maturin-linux:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        target: [x86_64, aarch64, armv7]
    steps:
      - uses: actions/checkout@v4
      - name: Build wheels
        uses: PyO3/maturin-action@v1
        with:
          target: ${{ matrix.target }}
          args: --release --strip --locked --out dist --manifest-path chrs/Cargo.toml
          # sscache seems to be broken
          # sccache: 'true'
          manylinux: manylinux_2_28
      - name: Upload wheels
        uses: actions/upload-artifact@v3
        with:
          name: wheels
          path: dist

If I set sccache: 'true', I get this error:

/usr/bin/python3: No module named pip

With sccache commented out, the builds are successful. https://github.com/FNNDSC/chrs/actions/runs/8243573628/job/22544388834

I'm getting this error too. But, I think the error in sscache is just a duplicate of an error that happens earlier in the build:

So, whatever image is being pulled (quay.io/pypa/manylinux_2_28_x86_64:latest) doesn't seem to include pip?

The other branch of my matrix build works fine with ghcr.io/rust-cross/manylinux_2_28-cross:aarch64.

I'd recommend we rename this bug to "No module named pip for x86 manylinux_2_28".

Interesting. trying out the broken image:

Not sure why they changed that. Does it have ensurepip? Or maybe we need to yum install python3-pip.

To help with working around this, I've made this: #264

Installing python3-pip did not work and somehow installed an outdated version of Python 3 and pip for me. python3 -m ensurepip did however work.
