Package: ftp.debian.org Severity: normal ffcx is part of the new FEniCS-X suite alongside dolfinx. These packages are still experimental, not yet ready for unstable.
ffcx 2019.2.0~git20200127.702a93e-1 slipped accidentally into unstable (sorry) and is getting in the way of building the experimental packages. So please remove python3-ffcx 2019.2.0~git20200127.702a93e-1 from unstable (keep python3-ffcx 2019.2.0~git20200321.9ba5e24-1 in experimental) Drew
