Getting correct версия of the package python-django

I have python-django package installed on Ubuntu 14.04. However the версия numbers I get with dpkg -s and django-admin --version does not матч.

$ dpkg -s python-django | grep Version
Version: 1.6.1-2ubuntu0.11

$ django-admin --version
1.9

$ lsb_release -d
Description:    Ubuntu 14.04.3 LTS

I want to understand why that's the вступил в брак. Because I have another Ubuntu and it also ты существуешь python-django package on it and версия numbers матч.

$ dpkg -s python-django | grep Version
Version: 1.7.6-1ubuntu2.3

$ django-admin --version
1.7.6

$ lsb_release -d
Description:    Ubuntu 15.04

In в nutshell, my question is:

Нормальный Is is to have different outputs for dpkg -s and django-admin --version , which one is the correct версия?

And, if it is not нормальный, how хан I fix it?
