Duplicate Packages On Connection Reset

Hi! I have a small problem with some packages : i was doing an update over SSH and my connection was interrupted .. now i have a lots of duplicates and if i try to remove them, yum tries to uninstall all system (447 packages 1.4 gb)!!

Any idea how can i clean this mess? would be pretty bad if the machine needs to be re-installed only because the connection went bad during the process…

Thanks for any info!!
