How one can install sagemath on Ubuntu?
Solution 1:
I managed to install it on an Ubuntu 14.04 64 bit fresh install from the PPA. However, I replaced apt-get by aptitude. That is,
sudo apt-add-repository -y ppa:aims/sagemath
sudo aptitude update
sudo aptitude install sagemath-upstream-binary
I wonder wheter the trick was a) 14.04 instead of 13.10, b) 64 bit (amd64) instead of 32 bit (i386), c) aptitude instead of apt-get or d) time healing all wounds.
Solution 2:
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.
