Cannot upgrade pyhon-html5lib

Question

on my Ubuntu 14.04 LTS when I run: dpkg -l python-html5lib I'm receiving:

||/ Name                                          Version                     Architecture                Description
+++-=============================================-===========================-===========================-===============================================================================================
ii  python-html5lib                               0.999-3~ubuntu1             all                         HTML parser/tokenizer based on the WHATWG HTML5 specification (Python 2)

Why I'm not able to upgrade it to the newest 0.999999999 using

sudo pip install html5lib --upgrade ?

My pip version: pip 9.0.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)

Answer 1

There is a difference between pip and apt-get packages. It looks like apt-get repository is not always up-to-date with packages. I found out the answer here: https://askubuntu.com/a/431811 and eventually I'm using pip to manage python packages.
