Gavin, thank you for substantial answer.

By the way, will X desktop start automatically after installing
these packages?

I forgot to mention that I'd inserted the Ubuntu Alternate CD
used for installation. May it be the matter?

I can't reproduce the error now since I'm far from the server.
But it catched on edubuntu-artworks and slocate packages,
and a keyword was 'diverse' (or 'disperse' - sorry for my weak
memore).

I tried both, no success.

I think RAID(1,5) is a must for a server engaged in education.
Moreover, provided a server has two or more disks the installer
must suggest to configure softRAID and of course LVM
(regardless of quantity of disks).
In addition, as Edubuntu intended for education it should
educate from the very beginning, i.e. installation. I myself
had first known of LVM when installing ScientificLinux (RedHat
derivative).
