[PKG-Openstack-devel] Bug#841516: python-dogpile.cache: FTBFS (AssertionError: 1 != 0)

[Santiago Vila]

Package: src:python-dogpile.cache
Version: 0.6.2-3
Severity: serious

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

--------------------------------------------------------------------------------

The relevant part of the build log is included above.

This also fails in reproducible builds:

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/networking-arista.html

but the errors are different (?). If you plan to disable the tests that fail until we know
why they fail (I always recommend that, and I think you already do that as a normal thing),
please take a look at all the available build logs.

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.

Thanks.
