Hi Santiago, I have uploaded what I believe is a fix for #835177. Though as I am not sure how to reproduce your build env, it'd be really nice if you could try to build aodh 3.0.0-2 and check that the bug is really closed.
If that is the case (that my change fixes the FTBFS of aodh in your env), then I will apply the same kind of fix for #835178 and #835179. Thanks a lot if you can help here, Cheers, Thomas Goirand (zigo)
