Kevin, It is not your fault!
py-cython and py-cython-devel (cython 3.0.x) are incompatible, but the many packages haven’t been updated and still use the legacy version. This needs to be fixed upstream. py-yaml still needs py-cython, whereas py-astropy has been updated and requires py-cython-devel. However, as both packages install into the same location, you get a deadlock. I work around this issue, by deactivating the version not needed at the time and activating the needed one. YMMV.
