For anyone having issues with tweak o.... Delete everything from /var/cache/apt/archives/ ****EXCEPT 'partial' directory. Turns out you need that I also ran apt-get update as I killed the store by removing that partial directory and wanted to see what was going on... may need to run that too. It seems that if anything is already in /var/cache/apt/archives/ the script will just jump directly to the "Your application catched successfully!" message.
apt-get clean
On a random note, any chance of getting 'catched' changed to 'caught' in that message?
nano /opt/N9QTweak/OVI/catch_deb.sh
apt-get install nano
