The catalog is littered with clashing updates, bad installable/installed rules, circular references, critical updates that don't supersede or expire previous ones, literally dozens of Hitachi firmware updates.
Frankly it's a mess.
The advice to expire the updates is incorrect. I am now in a mess as i cannot republish to my WSUS server because the updates are expired on the server.
Does anyone know how to republish the Dell catalogue once the updates have been expired in SCUP + WSUS?
Interesting that the catalogue is not fixed after 8 years.
