Upgrade lenny -> squeeze

I'm having an issue with my daughter's netbook that I just upgraded from lenny to squeeze. The main problem is that it is 2100 miles away. In any case, I did the upgrade according to the squeeze release notes. When I did the upgrade, I changed the sources.list to point to squeeze, including trinity. However, it deinstalled kde-trinity, kdemultimedia-trinity and kdewebdev-trinity. So after the upgrade, I tried to reinstall. # apt-get install kde-trinity kdemultimedia-trinity kdewebdev-trinity Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
