Bug ID: 2219334 Summary: python-cloudpickle: FTBFS in f39-python side tag with Python 3.12 Product: Fedora Version: rawhide URL: https://koschei.fedoraproject.org/package/python-cloud pickle Status: NEW Component: python-cloudpickle Assignee: lbalhar@redhat.com Reporter: thrnciar@redhat.com QA Contact: extras-qa@fedoraproject.org CC: epel-packagers-sig@lists.fedoraproject.org, jonathan@almalinux.org, lbalhar@redhat.com, python-packagers-sig@lists.fedoraproject.org Target Milestone: --- Classification: Fedora

python-cloudpickle fails to build with Python 3.12.0b3 in f39-sidetag

For the build logs, see: https://koji.fedoraproject.org/koji/buildinfo?buildID=2218638

To reproduce this locally you can do: fedpkg mock-config --target f39-python > ~/.config/mock/f39-python.cfg fedpkg srpm mock -r f39-python --rebuild $SRPM

Or you can submit a scratch build in side tag with: fedpkg build --target=f39-python --scratch --srpm

Once fixed, please submit the real build into side tag with: fedpkg build --target=f39-python
