ubuntu下networkmanager不让管理解决办法

今天安装了一台ubuntu 22.04的虚拟机，结果添加张网卡死活不自动获取IP，手工配置networkmanager也无法激活，还报不受管理。

弄了一个中午，终于弄好了。

• 关闭cloud-init

  echo "network: {config: disabled}" | sudo tee /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg

  sudo touch /etc/cloud/cloud-init.disabled

  sudo systemctl stop cloud-init-local cloud-init cloud-config cloud-final
  sudo systemctl disable cloud-init-local cloud-init cloud-config cloud-final

关闭后确认状态

cloud-init status

• 最终生效的配置，写入netplan配置文件

/etc/netplan/01-network-manager-all.yaml

network:
  version: 2
  renderer: NetworkManager
