```
For the current main branch the cpp compiled and installed. For some reason just for main branch I have this PETSc.h error. The v0.6.0’s python does work with pip install .
Anyone maybe know how to resolve this for Ubuntu jammy desktop?

What version of petsc4py and petsc are you running?
It doesn’t seem like there is anything that has changed Since the 0.6 release [History for python/dolfinx/wrappers/caster\_petsc.h - FEniCS/dolfinx · GitHub](https://github.com/FEniCS/dolfinx/commits/main/python/dolfinx/wrappers/caster_petsc.h)

So what I did to solve this problem is:
pip uninstall mpi4py, petsc4py and remove petsc stuff from ~/.local/lib/…/site-packages/petsc\*
Then I used spack to install main branch and activated the environment in the terminal. The main branch needs I think a version of petsc4py not available from apt at the current time…
