Hi,

just some ideas, maybe they help you:

How did you make the lists? I would use dpkg --get-selections > list.txt

How did you make the diff? unfortunately I'm not familiar with command 
line diff, but mayby the output from diff confused the apt-get command:

> apt-get install -y -d `cat diff_pkg_list`

for this the input should be a plain list of package names.

you can alternatively use the combination of "dpkg --get-selections > 
list.txt" and later "dpkg --set-selections < list.txt", followed by a 
"apt-get dselect-upgrade".

since you had dependency problems, it looks like there was something 
missing. perhaps the uni machine has a different sources.list or 
hand-compiled/local packages installed?

For this I would just copy all extra packages to one directory, open a 
terminal, cd to the directory and type
"dpkg-scanpackages . /dev/null | gzip > Packages.gz"

There should be one file named Packages.gz between all the .debs in this 
directory after that.

Then burn the whole directory to cd with nautulilus/gnomebaker/k3b etc

you can later add the cd to the apt repositories with "apt-cdrom add" in 
a terminal.

Hope this helps. Good luck for saturday!
