Hello, I recently had to reinstall firedrake, which went well, but then when I tried installing slepc using "firedrake-update --slepc" I got the following error. I am including the log file. Any idea what might be the problem? Cheers, Francis Failed to clone slepc using ssh, falling back to https. Successfully cloned repository slepc.
