notarizing DMG fails

[toolbook at kestner.de]

Hello,

 

I have signed and notarized several apps with Matthias tool - successful

Then I packaged theses apps with Packages and signed the package via
terminal - successful

Then I  put the pkg into a dmg via DMG canvas and signed the dmg via
terminal - successful

Then I uploaded the dmg for notarization via terminal. The upload was
successful, but the email from apple told me, that the upload was not
notarized and the logfile tells me:

 

Severity: Error

Path: "DGSlern_Update_1.0.0.4.dmg/DGS Lernprogramm 1.0.0.4 Update .pkg"

Message: The binary is not signed

 

This is a bit irritating. Has anybody anytime encountered such conflicting
messages?

Any idea, where to look for?

Thanks

Tiemo
