I just build a new server and once I was able to log on, I did a yum -y 

The download (~100Mb) and updates all completed.

It is now in the cleanup and hung on 56/77 it has been on that entry for 
a couple hours.

How do I recover from this?

close terminal window, open new and then:  yum clean  ???

Should I reboot prior to the clean?
