ubuntu bridges 安装问题

Question

我按照说明操作，但是没有效果。

这是我的原始00-installer-config.yaml文件：

# This is the network config written by 'subiquity'
network:
  ethernets:
    enp2s0:
      dhcp4: true
    enxc21a33ea90c1:
      dhcp4: true
  version: 2

...编辑之后的样子如下：

# This is the network config written by 'subiquity'
network:
  ethernets:
    enp2s0:
      dhcp4: no
    enxc21a33ea90c1:
      dhcp4: no
  version: 2
  renderer: NetworkManager
  bridges:
          br0:
          interfaces: [enp2s0]
          addresses: [192.168.8.108/24]
          nameservers:
                  addresses:  [8.8.8.8,4.4.4.4]

运行后出现此错误sudo netplan apply：

/etc/netplan/00-installer-config.yaml:11:15: Error in network definition: expected mapping (check indentation)
          br0:

有人能指出哪里出了问题吗？

Answer 1

Netplan（使用 YAML）对缩进很挑剔。尝试像这样格式化文件，看看是否有效：

# This is the network config written by 'subiquity'
network:
  ethernets:
    enp2s0:
      dhcp4: no
    enxc21a33ea90c1:
      dhcp4: no
  version: 2
  renderer: NetworkManager
  bridges:
    br0:
      interfaces: [enp2s0]
      dhcp4: no
      addresses: [192.168.8.108/24]
      nameservers:
        addresses: [8.8.8.8, 8.8.4.4]

br0:我发现的主要错误是和之间缺少缩进interfaces:。

此外，并不是说辅助 Google DNS 是8.8.4.4。 也不是4.4.4.4。
