Original: Kubuntu 's package manager has a category view very similar to that of the Ubuntu software center , the default web browser is now based on webkit , and many more features showcased in Ubuntu are being matched by those in Kubuntu , such as the upcoming wireless connection page in the installer discs . Kubuntu 's website also received a welcomed redesign .
Simplified: Because the only difference of Kubuntu and Ubuntu is the default software , you can turn an Ubuntu system into a Kubuntu system , or a Kubuntu system into an Ubuntu system , only by installing some software .
