this breaks sage, as it makes the symbolic link 'python' to point to 'python3' in SAGE_LOCAL/bin. To fix, it suffices to make it point to python2 instead: cd SAGE_ROOT # where your Sage is installed cd local/bin ln -sf python2 python Then everything works as before (and you may also use python3 script from 'sage -sh') Perhaps a proper fix would be to leave python symbolic link as it is.
