I couldn't add certain packages because of a dependecy issue. The error I was getting was:
Transaction Check Error: package kernel-2.6.18-1.2849.fc6 is already installed
file /boot/System.map-2.6.18-1.2849.fc6 from install of kernel-2.6.18-1.2849.fc6 conflicts with file from package kernel-2.6.18-1.2849.fc6

All I did was remove the kernel through the Add/Remove Software option under applications. Then installed the packages that have a dependency on the kernel and it reinstalled the kernel for me. Problem solved.

No you can't.

instead of deleting the post or editing it clear...
you could share with others not only the initial question, but how you resolved it, so other users could also benefit...

good day.
