Ubuntu Server 22中自定义网络接口无法显示的问题求助

我正在Linux上学习网络配置，在VirtualBox里装了Ubuntu Server 22，但遇到了个麻烦事：我想给系统加一个带静态IP的新网络接口，已经在netplan里配置好了，但重启系统后这个接口就不见了，而且执行netplan apply也没报错。

默认网络接口配置 #

# This is the network config written by 'subiquity'
network:
  ethernets:
    enp0s3:
      dhcp4: true
  version: 2

我的自定义接口配置 #

network:
    ethernets:
        enp0s5:
            dhcp4: false
            addresses: [192.168.2.202/24]
            routes:
              - to: default
                via: 192.168.2.1
            nameservers:
              addresses: [8.8.8.8,8.8.4.4]
    version: 2

netplan --debug apply执行结果 #

为什么我的自定义接口不生效？我哪里做错了？
