Yes, in the presence of channels this can be tricky. However, we are not committed to supporting third party channels when this results in problems on our end. We reserve the freedom to break third party channels. Konrad, going forward it might be reasonable to keep copies of required Python 2 packages in your channel. We aren=E2=80=99t going to remove Pytho= n 2 packages now, but in the future we may not be able to fix unmaintained packages and may have to remove them. -- Ricardo
