i even unchecked the third-party software, and checked everything on the "Ubuntu Software" and "Updates" tab. I had some problem broken link that says error can not download some links due to not being found. (this is a common thing with the Dell mini 9 users who are using the Dell's version of Ubuntu 8.04)
since it does download files like this, i think it does an incomplete update. i am not sure
thats why I have the third party software on, which is on by default on a factory restore from dell. (when i do this, i don't have the broken update links saying its not found.)
i still don't have firefox 3.0.4
