Packages in question originally were removed via TECH234439; however, once a new Package Server is added to an environment we see Package Servers attempting to download these packages. Package Server reports indicate there are 10 packages in a 'Not Ready' state across all Package Servers.
Failed to get manifest for c72e1ab5-f300-4e8c-88ca-baf90b5b4e46: System.IO.DirectoryNotFoundException: Could not find a part of the path 'D:\Program Files\Altiris\Notification Server\NSCap\bin\Win64\x64\Symantec Endpoint Protection\AvInventory'.
All of these packages are no longer needed if their respective solution is uninstalled. The problem is most or all of them have attributes and item references that make them difficult to delete. Ergo we ended up with a lot of packages that take up space and, more often than not, foul up the Package Refresh process.
For the time being please apply the following workaround.
These packages should no longer get restored once a new Package Server is added to the environment.
