[Santiago Vila]

Package: src:gnocchi
Version: 3.0.0-2
Severity: serious

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
but it failed:

This is just how the build ends, not necessarily the relevant part.

I've put several build logs here:

https://people.debian.org/~sanvila/build-logs/gnocchi/

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the page for this package.

The bug should be reproducible with sbuild on a single CPU virtual machine.

Note: My build history is like this:

[...]
Status: successful  gnocchi_3.0.0-2_amd64-20170122T094410Z
Status: failed      gnocchi_3.0.0-2_amd64-20170126T170124Z
[...]

where every previous build was ok and now it always fail. Maybe some
build-dependency entered testing between 2017-01-22 and 2017-01-26
which is related to this failure.

Thanks.
