Hi Marcelo, the error message indicates you need a component called
CGAL to generate the mesh. CGAL has been replaced recently. This has
been a popular topic this month on this list, take a look at the
November archive:

so I followed the advice given on this list and reinstalled Fenics

sudo apt-get update

Now I am finding the following error:

Traceback (most recent call last):

NameError: name 'UnitCircleMesh' is not defined
