Bradje1,  Are you creating repositories and then using them in SUU?  Have you tried just using the latest version of SUU to update with, minus the custom repository? Or are you adding updates to the repository not found on the current SUU's repository? If so, what are you adding to the ISO?  If you are using an older version of SUU. This is 7.4 - [URL]#  Let me know. 
Hey, I have tried to download several SUU updates over the last week (different combinations of servers and packages eg R820 32 bit windows, r720xd 64 bit) and they are failing before finishing. Just wishing to know if that is happening at the Dell end also i.e. can any of you chaps download successfully using the latest Repository Mgr? Thx, John Bradshaw
SUU Downloads from Repository Mgr failing around 90%
