o/ pip 25.3 was released on Friday (who does Friday releases?!) and had removed support for the legacy `setup.py develop` editable install method in setuptools [1]. Now, thankfully most services seem to have listened to me [2][3] and the shouty warnings from setuptools/pip and migrated away from 'wsgi_scripts'. However, there is a good chance that older stable branches are missing these migration patches and consequently now broken. For example, it seems keystone is missing these changes on stable/2024.2, and attempts to deploy that branch currently fail with: Could not find versioned identity endpoints when attempting to authenticate. Please check that your auth_url is correct. Internal Server Error (HTTP 500) which, upon further inspection, will turn out to be a missing wsgi script: devstack@keystone.service[40466]: failed to open python file /opt/stack/data/venv/bin/keystone-wsgi-public We have already seen this pop up on the cluster-api-provider-openstack (CAPO) project [4], which is using the old stable/2024.2 (Dalmatian) release. I have proposed fixes to stable/2025.1 [5] and stable/2024.2 [6] to constrain pip on those older branches. This should fix the issue for everyone, provided you're not using a devstack plugin that re-updates pip. Individual services may also wish to backport the patches that added '$service.wsgi' modules if possible, to fix this for non-devstack use cases, but this won't be possible in all cases.
