Thanks, I'm trying to keep CentOS 5.5 from upgrading to 5.6 because of my issue with the time sync. I thought I had it figured out till today. I have tried google for help but with no luck. Can someone point me to a page or link that will give me a good idea as to how to stop the upgrade but still allow me to update my 5.5 packages? This is what I tried, that is not working
