I have 4 kubuntu breezy systems that I want to upgrade to dapper. I thought I could get the install CD and use it as an apt source so I could get most of the new stuff off the CD rather than the net. I ran apt-cdrom and I see the entry at the top of sources.list. I changed 'breezy' to 'dapper' in sources.list, and ran apt-get update and apt-get dist-upgrade. It seems to be pulling everything off the net. Have I done something wrong or was this a dumb idea to begin with? I am by no means an apt expert. Thanks, Patrick McCabe
