%paste magic function on ipython3

I'm using ipython3, installed on Ubuntu with apt-get. I can't use the paste magic function, it complains about missing Tkinter. But I do have Tkinter and the same thing works fine on ipython (2). What gives?

Python 3.2.3 (default, Oct 19 2012, 19:53:16) 
Type "copyright", "credits" or "license" for more information.

IPython 0.13.1.rc2 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.

In [1]: %paste
ERROR: Getting text from the clipboard on this platform requires Tkinter.

Solution 1:

minrk comment got me on the right track, and I've fixed it with the following package.

sudo apt-get install python3-tk

Solution 2:

To be extra clear: wim's answer also works for python2.7, to cover all versions simply run:

sudo apt-get install python-tk
