[Python-modules-team] Bug#958034: python-zeroconf: FTBFS: tests fail without networking

[Andreas Beckmann]

Source: python-zeroconf
Version: 0.25.0-1
Severity: serious
Tags: ftbfs
Justification: fails to build from source

Hi,

python-zeroconf/experimental FTBFS under pbuilder which defaults to
disable networking during the build. This causes some tests to fail:
