我需要isc-dhcp-server在 debianstretch 上安装，但无法正确安装该软件包。
apt-listbugs list isc-dhcp-server：

安装包后

安装包从源头(4.3.6版本)无法解决问题，有办法isc-dhcp-server在debianstretch上安装吗？

答案1
我一直在 Stretch 中使用官方 ISC DHCPd Debian 软件包没有systemd，并在 Debian 中使用它，并自 Debian 6 起升级特定的 DHCP 集群，没有遇到太多麻烦。
至于Stretch，我已经在上面使用isc-dhcp一年多了，我认为，因为我之前迁移是为了利用新版本，而不是组装我自己的 deb。 （我有一些与 Windows DHCP 客户端相关的原因）
通常这些类型的服务应该单独存在于一台机器中，因此我建议破例并使用带有 sysV init 实用程序的 Debian 服务器。
为此，您可以这样做：
sudo apt-get install sysvinit-core sysvinit
