[Libmesh-users] Error in libmesh + petsc (fail to convert SparseMatrix into PetscMatrix)

Hi,

I see this issue:

Failed to convert N7libMesh12SparseMatrixIdEE pointer to
PN7libMesh11PetscMatrixIdEE
The N7libMesh12SparseMatrixIdEE appears to be a

I am using libmesh master branch and petsc 3.15.3.

Any idea of what might be wrong?
