i have ubuntu 6.06 LTS installed. got the iso of 6.10 frm chip mag cd.i have burnt this image on a cd. how do i go about updating without using a net connection. i tried the commands sudo apt-cdrom add sudo apt-get update sudo apt-get dist-upgrade but it started downloading something from the net... i have a dial up conn.so it is not possible for me to update ovet the net. so how do i update just using the cd rom. also i have installed most of the restricted formats and softwares...will i have to install these all over again after updating.??
