hi everybody! i have installed debian version 6.0.2 on computer without internet connection. Also i have full set of DVD with 7.2.0 version. So - i want to upgrade the system. Im going to perform next steps: 1) remove all contents of /etc/apt/sources.list 2) add every DVD by "apt-cdrom add" command 3) #apt-get update #apt-get dist-upgrade Is this sequence of command correct (at least theoretically)? Is there pit falls? thanks in advance
