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

jaakko@jaakko-VPCEB1S1E:~$ sudo apt-add-repository -y ppa:aims/sagemath

gpg: keyring `/tmp/tmp7y1mxl/secring.gpg' created

gpg: keyring `/tmp/tmp7y1mxl/pubring.gpg' created

gpg: key BE796FF2: public key "Launchpad PPA for AIMS" imported

gpg: Total number processed: 1

gpg:               imported: 1  (RSA: 1)

OK

jaakko@jaakko-VPCEB1S1E:~$ sudo apt-get update
