This question already has an answer here:
I'm new to Ubuntu and Linux in general and coming from Windows I was wondering how to upgrade Ubuntu from one version to another. A new version is released each six months, right? So let's say I'm now running 13.04. When 13.10 will be released in october, how will I upgrade my system?
Will I have to reinstall my whole Linux, loosing all my programs or is there a way to simply replace 13.04 by 13.10?
