Perplexed

[Roger]

I just now used Fedup to update Fedora 18 to 19. It did it's thing 
quickly and efficiently and awaited a reboot.
I have both Ubuntu and Fedora on the hard drive. It boots to the Ubuntu 
grub from which I select  the Fedora install.
I selected Fedora spherical cow from the Ubuntu grub.
It booted to the familiar Fedora 18 and stayed there, everything works 
as previously but I have no idea whether it performed the update, as it 
says in the Fedora Fedup page.
I did see a very brief flash of what looked like an SELinux error message.

There are no messages in SELinux alerts.
What should I be looking for to resolve the upgrade please?
Thanks
Roger
