Install .deb on from CD-ROM while offline with default applications only
You have to install the .deb , and the dependencies, with dpkg. As long as you have all the dependencies, you should be able to install them with dpkg.
If you are having a problem, pastebin the command and output you are getting.
A more automated method would be to use Aptoncd
http://aptoncd.sourceforge.net/
In a new computer with the Internet, create a script with Synaptic package manager, download .deb files and burn them to a CD.
In other computers, put all the .deb files in a folder and
sudo dpkg -i *.deb
will work.
