我的 EC2 VM 版本是 Ubuntu 20.04.4 LTS（GNU/Linux 5.13.0-1021-aws x86_64）
答案1
它正在尝试通过云初始化服务访问一些元数据，但无法访问元数据服务，因此它继续尝试所有条目。您可以在以下文件中禁用云初始化服务：
/etc/cloud/cloud.cfg.d/90_dpkg.cfg
使用以下命令使其指向无任何内容：
echo 'datasource_list: [ None ]' | sudo -s tee /etc/cloud/cloud.cfg.d/90_dpkg.cfg
然后执行以下操作，以重新配置云初始化包：
sudo dpkg-reconfigure -f noninteractive cloud-init
但是如果您想恢复其默认值，可以使用以下命令：
sudo rm /etc/cloud/cloud.cfg.d/90_dpkg.cfg
sudo dpkg-reconfigure -f noninteractive cloud-init
答案2
在您的 EC2 实例的 cloud-init 配置中，某些命令正在尝试获取可能用于必要功能的令牌，但元数据似乎在您的 ec2 实例上被禁用。
您可以通过以下命令从您的 ec2 实例验证元数据是否已启用。
curl -v http://169.254.169.254/latest/meta-data/
如果它没有提供任何实例元数据，它将被禁用。您可以使用 aws ec2 命令行工具通过以下命令启用它。
aws ec2 modify-instance-metadata-options --instance-id {{instance_id}} --http-endpoint enabled
验证元数据是否再次启用，以及 cloud-init 命令是否能获取令牌。此后，启动实例不会花费太多时间。
