Yeah quite a lovely mess ain't it I was real impressed. You need to change to the /var/cache/apt/archives and then use dpkg -i --force-overwrite all_of_the_packages_in_errors_output use the entire name of the packages when doing this (dpkg -i --force-overwrite libice6_4.3.0-2_i386.deb libx11-6_4.3.0-2_i386.deb ....). Then once you are done dpkg --configure -a for the extra errors you will get due to some packages not being already configured. You may also want to remove and purge some small program then reinstall it just to make certain there a no stragglers that did not get configured.
