Ok, thanks... just updating the repository list via 'apt-get update' suffices. But for some reason, the first update did not complete succesfully... a second update try, though, went fine. After installing kchmviewer and fixing permissions of the /home/user directory tree, everything does appear to work fine.

Problem now is that the kchmviewer install drags in a lot of flotsam... flotsam which Qole had skillfully weeded out in the original debian-squeeze image.
