Ignoring widget's intense desire to start a flamewar, I'd reccomend doing some tests. Check, does internet work in firefox/konqueror? If no, then there's no problem with adept, it's just that you don't have internet hooked up with yet, which opens a whole new kettle of fish, and we'd need way more details to fix.
If internet does work in a browser, I'd reccomend checking what your repository settings are. What are the contents of /etc/apt/sources.list?
