Owen,

I'm guessing you don't care about running in parallel, at least not immediately, so don't let this stop you from getting started.

If it really bugs you, make a 16.04 virtual machine instead. This is the most recent LTS (long term support) Ubuntu release, and gets maintenance updates for 5 years from April 2016, by which time you'll have graduated. Hopefully ;) On the other hand, 17.10 only gets updates for 9 months from October 2017.

(I'm assuming you're running a VM just for Firedrake, not for anything else you do)

All the ubuntu packages that link against MPI are built against OpenMPI. We need to be very careful that when we install on such systems that we don't accidentally end up getting the wrong one.
