Netplan什么都不做

Question

我有这个配置

network:
  ethernets:
    eno1:
      dhcp4: no
      addresses: [192.168.0.103/24]
      gateway4: 192.168.0.1
      nameservers:
          addresses: [8.8.8.8,8.8.4.4]
  version: 2
  renderer: networkd

然后我做了：sudo netplan try并按ENTER，最后按i sudo reboot或shutdown并手动启动

当机器重新启动时，ip总是192.168.0.102。

会有什么问题？

Answer 1

我已经找到了解决办法。我正在运行这个博客文章中的自动桥设置：https://octetz.com/docs/2020/2020-11-13-vm-networks/

因此，我的网络配置来自networkd /etc/systemd/etc/2-br0-dhcp.net：

[Match]
Name=br0

[Network]
DHCP=ipv4

所以我刚刚把这个改成：

[Match]                                                                                                  
Name=br0                                                                                                 
                                                                                                         
[Network]
