Ubuntu Server 18.04.1 分配后无法保留静态 IP 地址

我正在尝试为我的家庭实验室服务器分配一系列静态 IP 地址，以便我可以运行媒体服务。

我编辑了/etc/netplan/以下内容：

01-netcfg.yaml：

network:
version: 2
renderer: networkd
ethernets:
    enp0s20f0:
        dhcp4: no
        addresses: [192.168.0.100/24]
        gateway4: 192.168.0.1
        nameservers:
            addresses: [192.168.0.1,8.8.4.8,8.8.8.8]

然后我对分配的另外三个端口重复此操作。例如，02-netcfg.yaml等等。

当我跑步时

sudo netplan apply

我获得了正确的 IP 地址。
几分钟后，我丢失了分配的数字，并从路由器的 DHCP 中获得了新的 IP。

我也尝试过通过路由器设置静态 IP，但遇到同样的问题。

有什么想法吗？
（我很乐意根据需要提供更多日志。）

更新：输出自syslog

答案1

这可能是一种可以NetworkManager实现这一点的服务。就purge这么办吧，希望它能发挥作用。

答案2

查看 netplan 上的这个相关错误...

如果您仍然遇到 netplan 问题，您可以轻松迁移回 ifupdown。我确实这样做了。
