In my conf.py it says I should see the documentation for a list of builtin-themes. Now my first google hit leads me to http://www.sphinx-doc.org/en/stable/theming.html#builtin-themes . There are a bunch of themes in there which my sphinx does not know about. For example 'classic'.
in conf.py
html_theme = 'classic'
On my shell I do: sphinx-build -b html source build
writing output... [100%] index
Exception occurred:
