I tried the online update from 7.10 to 8.04 but it stopped about half way and never got going again . So i waited about 45 minutes then went and downloaded the dvd and used that as a clean install . It works very good, I am pleased with the way hardy is snappy it guess the word. But i could not upgrade from 7.10 to 8.04 online -- yes this is as most of the previous ones were also. All in all the dvd install went very well Except trying to update the mirrors. That never happened it just stopped for about 40 minutes, i then unhooked the ethernet cable and started over and went perfectly that way , updated the sources after the install was done.
