Please note Ubuntu/Kubuntu "Dapper Drake" is not yet a final product and the available previews do not reflect the quality of the final product. Also this quick glance is not meant to divide Ubuntu and Kubuntu into separate distros; they are indeed almost identical to each other except the default desktop for Ubuntu is Gnome whereas KDE is Kubuntu's default desktop.
"I hope I am not making a mistake." Those were my thoughts when I decided to upgrade my Ubuntu system (5.10 Breezy Badger) to the still under construction 6.06 (Dapper Drake)
At the time I was not sure should I do a clean installation (download a +-650MB ISO, format etc) or edit my sources.list and do an apt-get distro-upgrade.
Since I had already used my system for a while I was not in the mood to start over so I did what some people might think is unthinkable (stupid) I went the upgrade root.
I edited my sources.list and replaced all repositories with dapper drake. Then launched Synaptic and chose "mark all upgrades." Synaptic informed me I would have to download approximately 680MB's worth of software. Certain packages could not be upgraded and had to be removed from the system.
Once all the files had been downloaded Synaptic began installing/upgrading the system.
