Hello again, Yesterday I started setting up a new ubuntu laptop running 16.04. I started to install firedrake and it took a long time to do the petsc install but seemed to get past that but then something went wrong, see below. Any ideas what might be wrong? Also, if I wanted to finish the install is there a way to continue rather than starting from scratch? Cheers, Francis Cloning libspatialindex Failed to clone libspatialindex using ssh, falling back to https. Successfully cloned libspatialindex branch master.
