Hello, On a different note, I needed to do a fresh install of firedrake and most seemed to go well but when I try and update to include slepc, I get the following error. Can anyone say if there is something badly set up on my end? Francis Installing SLEPc. Updating the git repository for slepc No need to rebuild SLEPc Installing slepc4py. Cloning slepc4py Failed to clone slepc4py using ssh, falling back to https. Successfully cloned repository slepc4py.
