I followed the link "Linux binaries" from the Download page, which leads to a page titles "Binaries for Linux" for which I do not have enough karma to post the exact url, but it is sagemath dot org slash download minus linux dot html. As recommended I downloaded the torrent version of sage-8.2-Ubuntu_16.04-x86_64.tar.bz2 But ./sage gives this result:
~/Documents/SageMath $ ./sage
RecursionError: maximum recursion depth exceeded during compilation
************************************************************************
It seems that you are attempting to run Sage from an unpacked source
tarball, but you have not compiled it yet (or maybe the build has not
finished). You should run `make` in the Sage root directory first.
If you did not intend to build Sage from source, you should download
a binary tarball instead. Read README.txt for more information.
