Hi! While rebuilding the python related packages against the Python 3.15rc1 version we found that pyxdg fails to build from source [1]. The upstream repository recently applied a fix that solves this problem [2]. I applied the upstream fix in the sandbox [3] to be able to build the packages that depend on pyxdg, please consider applying the patch to support the upcoming 3.15 version. Happy hacking, [1]: https://debusine.debian.net/debian/r-python-python3.15/artifact/4341416/ [2]: https://gitlab.freedesktop.org/xdg/pyxdg/-/commit/63033ac306aa26d32e1439417e59ae8f8a4c9820 [3]: https://debusine.debian.net/debian/r-python-python3.15/
