Comment 49 for bug 1306991

Tried to do the same as #48 to fix pip errors on my Ubuntu 15.10 (upgraded from 14.04/15.04).

This does not work :

$ sudo apt-get purge -y python-pip
$ sudo apt-get -y autoremove
$ sudo apt-get install -y python-pip
$ pip --version

Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()
[...]
    from pip.download import path_to_url
  File "/usr/lib/python2.7/dist-packages/pip/download.py", line 25, in <module>
    from requests.compat import IncompleteRead
ImportError: cannot import name IncompleteRead

However, this works:

$ sudo apt-get purge -y python-pip
$ sudo easy_install pip

Now I have a fully function pip
