I am trying to install python-pip. But I am getting the following error:

root@w.x.y.z:~# apt-get install python-pip
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 python-pip : Depends: python-setuptools (>= 0.6c1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I tried all the solutions possible via command line mentioned here. But its not working. Please can someone help? Following is my sources.list:

First remove the python-pkg-resources completely using

 sudo apt-get purge python-pkg-resources

Once completed successfully, first run

  sudo apt-get -f install

then

   sudo apt-get install python-pip
