I just upgraded from 2.2 to 3.1 on Woody. Since the README on ktown doesn't have specific 2.2.2 --> 3.1 advice, here's what I encountered.
(I haven't really followed any of the 2.2 threads, so apologies if I'm repeating what's already been said.) The only problem I ran into was with kdelibs3. I _think_ that a smooth upgrade path would be to first purge kdelibs3 then do the apt-get stuff: dpkg --purge --force-all kdelibs3 apt-get update apt-get install kdebase kdm I'm not sure if this would really work, since I tried to do apt-get install first, then used dselect to remove kdelibs3 and install kdelibs4 at the same time, then did apt-get install kdebase kdm again. (Thanks Ralf!!) BTW, the README lists kdebindings as one of the KDE packages, but apt-get can't find it... M.
