Ut_Fleet,   Sorry for the delay in responding. The link has indeed been removed and is causing the issue in OM Ent. The new catalog looks to be set for release in the next week or so, which should resolve the issue
Across multiple instances of OpenManage Enterprise 3.3.1 (Dell appliances), we are getting package download failures, specifically for the OS Collector 5.0 package for R430s (narrowed it down one by one to that update in particular).  Can Dell look into this as it is making all of our automation break down due to this one package.  This started failing on Friday (2/21) and has continued through to today. As a side note, it would be really nice if the Job Execution Details said which package failed to download, instead of just saying "One or more" failed...
