Você pode usar pip3para instalar o ipython.

sudo apt-get install python3-pip
sudo pip3 install ipython

Você precisa instalar o python-sip-dev ou /usr/bin/sipnão existirá.

Julian Taylor tem PPAs para IPython:

IPython estável (ppa: jtaylor / ipython)

Todas as noites do IPython (ppa: jtaylor / ipython-dev)

Para oníricos, a instalação ipython3de qualquer um desses itens fornece o terminal padrão IPython. O console Qt e o notebook HTML funcionam no Python 3, mas você precisará instalar algumas dependências. Existem instruções no wiki do IPython .
