No, it is not needed, but it is safer if you plan to have many users of your server, especially users you do not trust. To figure out what is wrong, you need to type: "sage -sh" on the command line, then type the thing from the error message, which may be this: sage-native-execute ssh -t sage1@localhost "/home/engineer/sage-4.7.2-linux-32bit-ubuntu_10.04_lts-i686-Linux/sage -python" This can't possibly work if you have not created an account called "sage1" and set up password login from your normal account to sage1@localhost using ssh keys. Setting that up involves using the command "ssh-keygen -t rsa -b 1024" and editing the file $HOME/.ssh/authorized_keys in the sage1 account. > and what's wrong with my installation.
