[PKG-Openstack-devel] Bug#834840: neutron: FTBFS too much often (ImportError: No module named pep8)

[Santiago Vila]

Package: src:neutron
Version: 2:8.1.2-1
Severity: serious

Dear maintainer:

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

Because this source package only generates "Arch: all" packages, this
is the same as a FTBFS bug in the usual sense, and the fact that I was
doing "dpkg-buildpackage -A" does not mean anything special.

Thanks.
