The code that gets "additional files" during package install does not pass failure codes back up to the overall package install routines. So if there is an error getting one of the additional files it is reported in the text progress display but the installer code thinks the install succeeded. You have to watch the text output carefully and then go back and delete the package and try again if "additional files" went wrong.

I think this has been an issue for a while, maybe on 2.2.*? But it now happens more for me, I suspect because of the lower general timeout for making connections.

Sample output from today at a site that has crud internet (usually has packet loss):
