Nope. They don't. I reinstalled a few times while figuring out what the real
issue is.

Perhaps you don't have python2 installed. The official stable package looks
like it probably works fine if you don't have python2 installed.

But if you do have both official pythons installed from the stable
repositories, as I do, then /usr/bin/python points to python2 (at least it
does here) so that when jupyter tries to create a python3 notebook and
executes "python", then it executes python2,not python3, and hence there's a
rapid failure.

Easy to fix, per bug 913110, but it /is/ a bug.
