Signing and authenticating .deb repositories is not supported or tested 
in Yocto. Do not take Ubuntu instructions for it, they are not relevant 
and not likely to work.

You can use .deb repostories without having them signed, or you can 
switch to rpm packaging (and master branch) where signing should work. 
Or you can figure out where that error comes from and fix it and create 
a patchset, but it's up to you to do the investigation and fixing.
