If you installed the package then your package manage will update it automatically as the PPA is updated. You shouldn't need to do anything with a downloaded .tar file. Just run a sudo apt-get update and then a sudo apt-get upgrade wine1.3 from terminal. ( This assumes you installed through the PPA (http://www.winehq.org/download/ubuntu) in the first place. And it isn't unique to wine. http://ubuntuguide.org/wiki/Ubuntu:Natty#Apt_and_Package_Basics
