When upgrading to kubuntu-desktop, a dist-upgrade produces the following errors, preventing the proper install of libavahi-compat-libdnssd1_0.6.13-2ubuntu2_i386.deb and subsequently prevents the install and configuration of ksysguardd and ksysguard (and ultimately kubuntu-desktop as well) ... when trying to --unpack libavahi-compat-libdnssd1_0.6.13-2ubuntu2_i386.deb, an error is produced stating that it is trying to
overwrite `/usr/lib/libdns_sd.so.1', which is also in package bonjour
