Huh? "Installer.mpkg uses a deprecated pre-10.2 format (or uses a newer format but is invalid)."

I've scoured JAMF Nation as well as the interwebs and found some references to this error, though I haven't found any real solutions.

"2014-12-11 15:27:01.734 installer[41057:6e03] Package /Library/Application Support/JAMF/Downloads/IBM Notes Installer.mpkg.unzip/IBM Notes Installer.mpkg uses a deprecated pre-10.2 format (or uses a newer format but is invalid)."

We are receiving this error on nearly every machine that runs this policy. Which btw is installing the latest version of the email client that we currently use. Can anyone shed some light on what the Root cause of this error is?

I'm happy to provide more info if needed, just wanted to keep this post as short and sweet as possible.

Thanks!

Can you manually download the package from your share point and run it successfully? It sounds like the mpkg is damaged to me and may need to be re-uploaded, or you need to obtain a new copy if its vendor supplied.

I thought uses a deprecated pre-10.2 format (or uses a newer format but is invalid) was a spurious error, safe to ignore?

I thought (bad prefix on a tech forum, I know) that the message simply indicated the installer didn't have a valid signature, which is common. That could be checked by looking for the lock when opening it in Installer.app, or with codesign -v in the terminal.
