This is, generally impossible for ubuntu/debian based distributions.

Because ubuntu is a huge distribution which is more than 60GigaBytes.
the installation CD/DVD is only a tiny subset of the ubuntu
distribution itself and every installation of kubuntu or ubuntu are
"partial install".

After you had done your flavor of tiny installation (kubuntu CD could
be called a "flavor" of subset of the ubuntu), you almost always need
to install additions from a network called "ubuntu repository".

When upgrade, you get a CD which contains only a tiny subset of the
whole ubuntu, and many packages cannot get upgraded from CD if you do
not have internet access to ubuntu repository.

If you do have direct internet access to ubuntu repository, it seems
that it makes no sense providing such a CD. because upgrade from
internet is much easier and more stable.


If all you want is to upgrade multiple computers without download
those packages multiple times, the best way IMO is to set up a cache
proxy server which caches all downloaded packages and all computers
can upgrade quickly.
