which are the different ways i can update software catalog?

Question

while facing problem(s) with software center 5.2.6 on ubuntu 12.04, i reinstalled the software center and executed following command on gnome terminal $ sudo dpkg --configure -a

Setting up software-center (5.2.6) ... Updating software catalog...**this may take a moment.**

However there is no or little beyond this point.

Is there any other way to update software catalog? because every other time i open up software center it keeps on crashing.

What about this script which solves Hash sum mismatches too :

#!/bin/sh
sudo rm -rfv /var/lib/apt/lists/*
sudo apt-get update
