Authentication Error After Updating up2date

[Robert L Cochran]

I did an rpm -Fvh of up2date-3.9.20-2 and up2date-gnome-3.9.20-2 in my 
Severn installation and then tried to run up2date -u.

I now get this error message:

There was an authentication error: Unable to authenticate.

What have I done wrong?

Thanks
