Package: fenics-basix Version: 0.3.0-11 Severity: serious Justification: rc policy - "Packages must be buildable within the same release."
Your package build-depends on python3-numba. Unfortunately numba is not ready for python 3.10, it has been removed from testing and since the recent upload of python3-defaults it is no longer installable in unstable. Looking at your package, it appears that numba is only used for build-time testing and the build-dependency is already limited to a subset of architectures, so I would suggest that the most sensible thing to do is to drop it for the time being until a version of numba is available in Debian that works with python 3.10.
