Keep watch also on the version of python3-ffcx. I've been updating the 
fenics-x packages to work with basix. This is probably not what's 
affecting you though (it might affect testing users who pull packages 
from unstable).

Curiously, my system now gives a completely different gmsh error (gmsh 
4.7.1+ds1-2).
gmsh itself is broken:

$ gmsh
gmsh: symbol lookup error: /lib/x86_64-linux-gnu/libgmsh.so.4.7: 
undefined symbol: _ZN4voro20voronoicell_neighborC1Ev
