Updating kde

I'm using synaptic to update from kde 3.2.1-63 to kde 3.2.2-8 but I keep getting rejected by conflicts like this: While preparing for installation: file /opt/kde3/share/apps/kdisplay/color-schemes/Plastik.kcsrc from install of kdebase3-3.2.2-8 conflicts with file from package plastik-0.3.9-0.pm.0 What should I do about this? Thanks, Jerome
