Python 2 reached upstream end-of-life in January 2020. In Fedora Rawhide, it's now provided from the compat package `python27`. Packages that only use Python 2 at build time, like openni-primesense, had a general exception to keep using it in Fedora 31. Now, the dependency should be removed. Switching to Python 3 seemed easy to me (though I don't necessarily know much about openni-primesense). So I opened a pull request: https://src.fedoraproject.org/rpms/openni-primesense/pull-request/2 Could you merge it? If not, if it's possible that the Python 2 build dependency won't get removed in Fedora 33, please let us know; the package will need a FESCo exception. If you need anything from us, or something is unclear, please mention it here.
Thanks for the patch/PR. Despite what the openni-primesense README says, it seems that Python isn't required to build this package at all. I've removed the python2 BuildRequires altogether. https://koji.fedoraproject.org/koji/taskinfo?taskID=43665532
