For the build logs, see: https://copr-be.cloud.fedoraproject.org/results/@python/python3.10/fedora-rawhide-x86_64/01865197-python-pandas/ For all our attempts to build python-pandas with Python 3.10, see: https://copr.fedorainfracloud.org/coprs/g/python/python3.10/package/python-pandas/ 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 3.10: https://copr.fedorainfracloud.org/coprs/g/python/python3.10/ Let us know here if you have any questions. Python 3.10 will be included in Fedora 35. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.10. 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.

Dear Maintainer, your package has an open Fails To Build From Source bug for Fedora 34. Action is required from you. If you can fix your package to build, perform a build in koji, and either create an update in bodhi, or close this bug without creating an update, if updating is not appropriate [1]. If you are working on a fix, set the status to ASSIGNED to acknowledge this. If you have already fixed this issue, please close this Bugzilla report. Following the policy for such packages [2], your package will be orphaned if this bug remains in NEW state more than 8 weeks (not sooner than 2021-03-03). A week before the mass branching of Fedora 35 according to the schedule [3], any packages not successfully rebuilt at least on Fedora 33 will be retired regardless of the status of this bug.

According to koschei, python-pandas is building again in rawhide.
