Missing umfpack

I am not a regular Linux user, so this may be a stupid question.

I am trying to run a script on an Ubuntu Linux machine (5.15.0-76-generic) and have installed ngsolve using pip3 (6.2.2304). I try


and get the error message

netgen.libngpy._meshing.NgException: SparseMatrix::InverseMatrix: UmfpackInverse not available

Can you help me get the necessary component for ngsolve?


Hi Peter,
We didn’t yet manage to provide the pip installer with umfpack on Linux yet, but you can use pardiso instead.
