The Package Servers are repeatedly trying to download a package that no longer exists. The package did exist at one time but it was deleted from the SMP console.
It is not in the server's snapshot directory and cannot be found in a query of the codebases of the CMDB.
The error that continues to show up on the package servers is "Error while downloading package. No package sources returned by server".
Release: 8.x
The package is stuck in the Secure Storage folder.
First, check the KB 181405 and if this doesn't resolve the issue then follow the steps below:
If still the package comes back to the package server and retries downloading, check the UrgentList.xml on the Package Server. It is possible that there will be no policy but still, we have it in the UrgentList. If so, Delete the UrgentList.XML located in 'C:\Program Files\Altiris\Altiris Agent\Package Server Agent\PackageStatus\UrgentList.xml'.
Note:
Some information regarding standard packages and when those packages are considered "Urgent":
{{ Skip removal of urgent package not in the policy: {ff99ff26-c91f-47cc-bd5d-2415e482180a}}}
This means two things:
Unfortunately, there is no way to remove just one package from "UrgentList.xml" since it exists the same way as all the policies and its hash is being verified each time. The only way to remove a package from that file is to remove the file itself.
When you remove UrgentList.xml, and since this package is not in the policy (check that just in case), the package should be removed from Agent UI as well upon PS start.
