Launchpad itself

The following packages cannot be authenticated

Asked by Azureiotsdk Team

When I submit my package I get an error on dependent packages within the same PPA.

WARNING: The following packages cannot be authenticated!
  azure-c-shared-util-lib azure-c-shared-util-dev azure-uamqp-c-lib
  azure-uamqp-c-dev azure-umqtt-c-lib azure-umqtt-c-dev
  sbuild-build-depends-azure-iot-sdk-c-dummy

after that I get the following error:

Errors were encountered while processing:
 /var/cache/apt/archives/azure-uamqp-c-lib_0.1.0-27_i386.deb
 /var/cache/apt/archives/azure-uamqp-c-dev_0.1.0-27_i386.deb
 /var/cache/apt/archives/azure-umqtt-c-lib_0.1.0-17_i386.deb
 /var/cache/apt/archives/azure-umqtt-c-dev_0.1.0-17_i386.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

Why would my packages not be authenticated if they exist in the same PPA?

Authentication warnings are a red herring in this case; you can ignore them. Your real problem is this:

You need to make sure that packages that you want to install together don't contain overlapping sets of files.
