No such file or directory: 'demo.html'

[rpanchal1996]

I am trying to run the interactive server, but when I navigate to the server URL, the page throws up a 500 code error (Internal Server Error).

The trace for the error is:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/bottle.py", line 862, in _handle
    return route.call(**args)
  File "/usr/local/lib/python3.6/dist-packages/bottle.py", line 1740, in wrapper
    rv = callback(*a, **ka)

Which is obviously caused by the missing demo.html file. Can you please help me out with where do I procure the file from?

I am running a Python3.6 on Ubuntu 16.04.
