Why is there no tkinter distribution found?

The Tkinter library comes in default with every Python installation

Try this:

import Tkinter as tk

Follow this guide to install "tkinter". However now with Python version 3.1 onwards, it is part of the standard python distribution.

You can also install it using sudo apt-get install python3-tk-dbg, if you are in virtualenv. (Same can be done for normal installation, not just virtualenv)

You should install

apt-get install python-tk

This should solve your issue
