This is my fault,

python-ipython accepts both python-prompt-toolkit-2 and the latest
version, python-prompt-toolkit (3), but some packages that depend on
ipython accept only python-prompt-toolkit-2.

I messed up with jupyter, I didn't realize that another input depended
on ipython also.

I'll try to fix it. I can't early this week, but I'll work on it
starting wednesday.

I'm sorry for the inconvenience.
