Found the issue, will be very likely fixed with the next release, the certificate was simply not included at all in the archive.

Had installed new version 20.0.7, too.

I have uninstalled the News app and started a new analysis. After that, the error disapeared.

15.3.2 includes the certificate and I could validate it on my own installation, no more signature errors
