I tried to install sagemath via command line but encountered a problem. Am I doing something wrong? I have Ubuntu 13.10.

I only saw this post now but the PPA doesn't seem to work, I just downloaded the latest binary version of Sage Math 6.1.1 and installed it for all users(only me) on my computer using symbolic link. I am using Ubuntu 14.04 Trusty. Perhaps you can use the cloud version.
