ec2 ubuntu 服务器 18.04 上出现 Cloud-init 相关错误

我的 EC2 Ubuntu 18.04 服务器上出现以下错误。如果有人知道原因和解决方案，请帮助我。

当我尝试时Cloud-init status我得到了status: error结果。

下面显示的错误日志来自/var/log/cloud-init-output.log：

目前，服务器已经正常运行。

我的理解是 AWS EC2 需要桥接。请尝试这个 .yaml 文件。保持精确的间距、缩进，并且不要使用制表符，因为 netplan 非常挑剔。

笔记：保留当前 .yaml 文件的备份，以防万一。

# This file is generated from information provided by the datasource.  Changes
# to it will not persist across an instance reboot.  To disable cloud-init's
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      match:
        macaddress: 02:9e:ef:ad:39:1a
      set-name: eth0
  bridges:
    br0:
      dhcp4: true
      macaddress: 02:9e:ef:ad:39:1a
      interfaces:
        - eth0

笔记：您可能需要创建/etc/cloud/cloud.cfg.d/99-disable-network-config.cfg

network: {config: disabled}

sudo netplan --debug generate

sudo netplan apply

reboot＃ 强制的

更新＃1：

OP 找到了下面解决该问题的命令......

$ sudo DI_LOG=stderr /usr/lib/cloud-init/ds-identify --force 
$ sudo cloud-init clean --logs 
$ sudo cloud-init init --local 
$ sudo cloud-init init
