Hi! While rebuilding the python related packages against the Python 3.15rc2 as the default Python version we found that pyqt5 fails to build from source [1]. While it works fine just building against 3.15 as one of the supported versions, it breaks when it's the default for two reasons: The error in the log is: dh_missing: error: missing files, aborting And this is due the new abi3t file that is generated when building against Python 3.15 and that is not getting installed. On top of this, I also had to add a patch to solve a missing cast (PyObject*) that Python used to do implicitly and now needs to be done explicitly. This patch should probably be forwarded upstream. I've applied these fixes in the sandbox [2] to verify that it builds successfully, please consider applying the patch to support the upcoming 3.15 version. Setting the severity to important for now. Once Python 3.15 becomes the default version this bug will become release critical. Happy hacking, [1]: https://debusine.debian.net/debian/r-python-python3.15/artifact/4751112/ [2]: https://debusine.debian.net/debian/r-python-python3.15/
