Oli, you need to specify a polynomial degree you want to use. If you have a look at step-2 (https://www.dealii.org/current/doxygen/deal.II/step_2.html), you see that it has a line saying
const FE_Q<2> <https://www.dealii.org/current/doxygen/deal.II/classFE__Q.html> finite_element(1); to create a linear finite element.
