Ubuntu :: How To Repair Broken Installed Update Packages

"the following problems were found on ur sytem: there are multiple versions of 'drakconf' in your system this package wont be cleanly updated unless u leave only one version." not only darkconf several other files too has the same error. how to uninstall duplicates?

i left the pclinuxos update (via synaptic pckage manager) and wen i came back i saw the pc had shut down, and the above and bottom toolbars has dissappeared. and the above error wen i start the package manager. how can i make a cd repair install? if this is the solution.

edit: i uninstalled duplicates but still the gnome deskop toobars still not there??
