I tried to run sudo apt-get install sagemath. It gives below error under ubuntu 16.04:

Reading package lists... Done Building dependency tree Reading state information... Done Package sagemath is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

E: Package 'sagemath' has no installation candidate
