python3-dolfinx 2019.2.0~git20200420.6043d6d-6 (armhf binary) in ubuntu groovy

 DOLFIN is the Python and C++ interface of the FEniCS project for the
 automated solution of differential equations, providing a consistent
 PSE (Problem Solving Environment) for solving ordinary and partial
 differential equations. Key features include a simple, consistent and
 intuitive object-oriented API; automatic and efficient evaluation of
 variational forms; automatic and efficient assembly of linear
 systems; and support for general families of finite elements.
 .
 This is the next-generation version of libdolfinx-dev (DOLFIN-X).
 The legacy version of DOLFIN is provided by python3-dolfin.
 .
 This is a base package depending on the dolfinx packages with
 real or complex number support. By default the version built against
 the preferred version of PETSc in /usr/lib/petsc is selected, but the
 alternative version can be selected by setting the environment
 variable PETSC_DIR.
