Unable to install packages

[John Perry]

I just installed Fedora 10 on my Sony Vaio laptop. Everything was fine until the system did an automatic update. Now when I try to use Packagekit  (System->Administration->Add/Remove Software) to add new software I get the following message. What is going on? What do I need to do to fix this? There are several packages I need to add to finish out the functionality of my laptop. I currently have SELinux disabled in the hope that it was the cause of the problem.  Please advise.
