On Ubuntu Server 12.04, I had this problem after installing a version of Python from source (Python3.4). 

Some of the comments here recommend installing Ipython and I want to mention that I have the same behavior even with Ipython. From what I can tell, this is a readline problem. 

For Ubuntu 12.04 server, I had to install <code>libncurses-dev</code> and <code>libreadline-dev</code> and then install Python from source for up-history (readline) behavior to be enabled. I pretty much did this:

<pre><code>sudo apt-get install libncurses-dev libreadline-dev
</code></pre>

After that, I deleted the previously installed Python (NOT THE SYSTEM PYTHON, the one I had installed from source!) and reinstalled it from source and everything worked as expected.

I did not have to install anything with pip or edit .pythonstartup.
