Re: problem updating from Edgy to Fiesty

If you're following the directions on the main Kubuntu page and have changed your sources.list as directed, you need to 'comment out' your sources.list lines that make reference to your CD ROM. To do this, go to Kmenu-->System-->Konsole. Type in

sudo kate /etc/apt/sources.list

and press enter. Look for the lines that contain CD ROM in them and place a # in front of them. For example if the line says

deb CD ROM archive.ubuntu.com/ubuntu/

(made that one up) adding the # would make it look like this

#deb CD ROM archive.ubuntu.com/ubuntu/

Do note where the # mark goes. Save and close and try all over again.
