Update to Sage 6.5 on Ubuntu 14.10
Hi,
My current version is Sage 6.4 on Ubuntu 14.10. The problem is that Sage is not updated by the update system of ubuntu and I didn't succeed in updating sage to the latest version by hand.
After executing the instructions there https://launchpad.net/~aims/+archive/...
sudo -E apt-add-repository -y ppa:aims/sagemath
sudo -E apt-get update
sudo -E apt-get install sagemath-upstream-binary
The system answer that "sagemath-upstream-binary is already the latest version".
Thanks for your solutions! Arnaud
