I am running Kubuntu Lucid.  I added "deb http://ppa.launchpad.net/kde3-
maintainers/ppa/ubuntu lucid main" to my sources, updated and ran "apt-
get install kubuntu-desktop-kde3".  However, it would not install:

kdelibs4c2a-kde3: Depends: kdelibs-data-kde3 (> 4:3.5.12) but it is not 
going to be installed
                  Depends: kdelibs-data-kde3 (< 4:3.5.13) but it is not going to be installed

So, I tried installing  kdelibs-data-kde3 but, again, nogo:

dpkg: error processing /var/cache/apt/archives/kdelibs-data-kde3_4%3a3.5.12-0ubuntu6+r1152788_all.deb
 (--unpack): 
 trying to overwrite '/etc/kde3/ksslcalist', which is also in package kdelibs-data 4:3.5.10.dfsg.1-3ubuntu2

Any advice appreciated.
