Build failure with Zesty

Hi,

I've a build failure on my ppa.

I'm packaging a python3 binding of a lib, so this lib is a depend of the binding.

I'm the author of the lib and the binding. The lib was published into the same ppa four hours before I put the binding.

Quote from the build log:
"Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 sbuild-build-depends-py3-oqapy-iproc-dummy : Depends: liboqapy-iproc0 but it is not going to be installed
E: Unable to correct problems, you have held broken packages."

The build log:
https://launchpad.net/~vincent-vandevyvre/+archive/ubuntu/vvv/+build/13351808/+files/buildlog_ubuntu-zesty-i386.py3-oqapy-iproc_0.2.2-0ubuntu2_BUILDING.txt.gz

My ppa:
https://launchpad.net/~vincent-vandevyvre/+archive/ubuntu/vvv/+packages

Note: The failure appears only for Zesty,not for Trusty and Xenial.

I don't have a machine with Zesty to test the installation of liboqapy-iproc, maybe the problem is from this lib.

Thanks for any advice.

Vincent
