Hi,
Moving forward with my current upgrades, I tried to upgrade our preprod Magnum to Caracal. Unfortunately, every components using the Magnum module fails with:
----
File "/usr/bin/magnum-api-wsgi", line 52, in <module> application = build_wsgi_app() File "/usr/lib/python3.9/site-packages/magnum/api/app.py", line 74, in build_wsgi_app service.prepare_service(sys.argv) File "/usr/lib/python3.9/site-packages/magnum/common/service.py", line 27, in prepare_service config.parse_args(argv) File "/usr/lib/python3.9/site-packages/magnum/common/config.py", line 32, in parse_args version=version.version_info.release_string(), File "/usr/lib/python3.9/site-packages/pbr/version.py", line 490, in release_string return self.semantic_version().release_string() File "/usr/lib/python3.9/site-packages/pbr/version.py", line 498, in semantic_version self._semantic = self._get_version_from_importlib_metadata() File "/usr/lib/python3.9/site-packages/pbr/version.py", line 483, in _get_version_from_importlib_metadata return SemanticVersion.from_pip_string(result_string) File "/usr/lib/python3.9/site-packages/pbr/version.py", line 156, in from_pip_string return klass._from_pip_string_unsafe(version_string) File "/usr/lib/python3.9/site-packages/pbr/version.py", line 163, in _from_pip_string_unsafe version_string = version_string.lstrip('vV') AttributeError: 'NoneType' object has no attribute 'lstrip' ----
It also affects magnum-db-manage where the traceback is litle bit different but the exception happens at the same place so I guess it is a common cause:
------
File "/usr/bin/magnum-db-manage", line 5, in <module> from magnum.cmd.db_manage import main File "/usr/lib/python3.9/site-packages/magnum/__init__.py", line 18, in <module> __version__ = pbr.version.VersionInfo( File "/usr/lib/python3.9/site-packages/pbr/version.py", line 505, in version_string return self.semantic_version().brief_string() File "/usr/lib/python3.9/site-packages/pbr/version.py", line 498, in semantic_version self._semantic = self._get_version_from_importlib_metadata() File "/usr/lib/python3.9/site-packages/pbr/version.py", line 483, in _get_version_from_importlib_metadata return SemanticVersion.from_pip_string(result_string) File "/usr/lib/python3.9/site-packages/pbr/version.py", line 156, in from_pip_string return klass._from_pip_string_unsafe(version_string) File "/usr/lib/python3.9/site-packages/pbr/version.py", line 163, in _from_pip_string_unsafe version_string = version_string.lstrip('vV') AttributeError: 'NoneType' object has no attribute 'lstrip'
------
For magnum-db-manage a workaround is to comment the __version__ line in __init__.but it doesn't help for the API.
I wanted to check in the Magnum release notes if I missed some requirements but unfortunately they are not linked from https://releases.openstack.org/caracal/#caracal-magnum and I was not able to locate them elsewhere...
Thanks in advance for any help/hint.
Best regards,
Michel
