To solve it we could either remove it from the build or rewrite the sources.list file a before installing packages:
sed -i 's/deb.debian.org/archive.debian.org/g' /etc/apt/sources.list
sed -i 's/security.debian.org/archive.debian.org/g' /etc/apt/sources.list
sed -i '/stretch-updates/d' /etc/apt/sources.list
