Basic example not working #141

I was now able to install awebox on Ubuntu 22.04 thanks to the latest fixes.

But running the first example 

python3 examples/ampyx_ap2_trajectory.py

fails with the following message:

INFO:   WARNING: Optimization of Trial (Ampyx_AP2) failed.

Any idea?

I do not have the closed source solvers installed, still waiting for a license...

Indeed this might be related to the missing HSL libraries. You might check if you can run the code if you change the following line:

options['solver.linear_solver'] = 'mumps'
