Public bug reported:
When SageMath is installed, Octave Symbolic will crash at first call and
then run properly.
Steps to reproduce on a fresh install of Focal Fossa.
1) Install 'octave-symbolic'.
2) Run Octave and create a symbolic object.
---within Octave---
pkg load symbolic
x = sym('x')
Symbolic pkg v2.8.0: Python communication link active, SymPy v1.5.1.
-------------------
3) Exit Octave and install 'sagemath'.
4) Repeat step 2).
---within Octave---
pkg load symbolic
x = sym('x')
Symbolic pkg v2.8.0: error: SymPy version Setting permissions of DOT_SAGE
directory so only you can read and write it.
1.5.1 found but is too old (1.2 required)
Try "sympref diagnose" for more information.
