This is a follow-up to my recent post. In that post, I reported the error
ImportError: No module named petsc4py.PETSc
when attempting to run demo_poisson.py.
Looking through a transcript of what I was doing, I realized that I had
successfully run one of the tutorial scripts: d1_p2D.py earlier in the
afternoon and it ran successfully. But then I upgraded my system using
synaptic and I noticed that I am now running fenics 1:1.3.0.2. After that
upgrade d1_p2D.py doesn't work. In fact, the single command "from dolfin
import *" fails with the message:
>>> from dolfin import *
Traceback (most recent call last):

Is it possible that something is wrong with the upgrade?
