Hi friends,

I am trying to upgrade my Backtrack ISO. I have the R1 and trying to download R2. I have a capped Broadband. So Googled and found zsync. I tried to use the file and see if I can download the updates and create a new ISO. I know I can just go ahead and easily upgrade using apt-get BUT I would be using this in multiple PC's and don't want to do this on every computer.

I have tried to use zsync but getting a lot of error's. Then somehow I have found some tut's and got a little bit closer. The error message that I got is

Code:
zsync -i '/home/*****/Desktop/Backtrack 5/BT5R2-GNOME-32.iso' 'http://www.backtrack-linux.org/ajax/download_redirect.php?id=BT5R2-GNOME-32.iso.zsync'
#################### 100.0% 0.0 kBps DONE    

Bad line - not a zsync file? "<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">"
So help me here please
