Users report Ubuntu Upgrade effortless
Preston L. Bannister says, "Fired up the “Update Manager”, and sure enough - it offered to install Ubuntu 6! Once started it ground away for something like an hour. After the Update Manager finished and a reboot - I had Ubuntu 6. This qualifies as the smoothest major upgrade ever - Linux or Windows!
I am impressed. Everything seems to work…"
Another reports, "The upgrades worked like a charm on both my desktop Dell and my Dell Latitude D610 laptop."
In a slightly older post, Mongoose states, "So far I'm really impressed with [kubuntu] and would recommend anyone to give it a go whether you've used Linux before and are pondering a new distro, or if you're thinking of giving it a shot for the first time."
