It seems to me that this is a problem with frozendict, not conda. frozendict PR : https://github.com/slezica/python-frozendict/pull/30 Thanks for the pointer. I pushed the patch to python-frozendict dist-git. This should be enough to get the new version in the python39 copr if I'm not mistaken. Orion, also consider contacting conda upstream about this, frozendict seems no longer maintained upstream and this will bite when installing stuff via pip (i.e. not from RPM). There should be a native implementation of immutable mapping in 3.9, but the PEP is not approved yet: https://www.python.org/dev/peps/pep-0603/ After frozendict there was another issue in conda itself. I pushed a commit to dist-git now. |

This will help create a clearer distinction between the concrete classes and the abstract base classes." For the build logs, see: https://copr-be.cloud.fedoraproject.org/results/@python/python3.9/fedora-rawhide-x86_64/01219465-conda/ For all our attempts to build conda with Python 3.9, see: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/package/conda/ Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.9: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/ Let us know here if you have any questions. Python 3.9 will be included in Fedora 33. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.9. A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon. We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.
