I would recommend using virtualenv to set up a Python environment with
SymPy 1.0. There are many resources for learning virtualenv, but briefly

  $ virtualenv ~/my-sympy-env  ## <- or choose whatever dir you like
  $ . ~/my-sympy-env/bin/activate
  $ pip install sympy
  $ octave
  ## do your Octave / octsympy work
  $ deactivate  ## or just exit the shell

The environment is self-contained and does not intrude on your normal
desktop or shell environment, so you'll have to activate it every time
you want to use this version of SymPy with Octave and octsympy.

And when you're ready to upgrade to Ubuntu 16.04, you can simply apt
install octave-symbolic and not deal with any of this.
