我无法通过Ubuntu EC2实例执行sudo apt-get更新。 当我跑步时-
sudo apt-get update
我收到以下错误：-

为解决此问题，我按照this进行了以下操作-
sudo sed -i 's/eu-central-1\.ec2\.//g' /etc/apt/sources.list
我重新启动了系统，然后重试。现在我在执行sudo apt-get update时收到此错误-

我该如何解决？

听起来您的实例无法访问互联网。
您的实例都需要位于公共子网中，并具有到连接的Internet网关的路由表：https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Internet_Gateway.html
或者您的实例在专用子网中，该子网需要一个到nat网关的路由表：https://aws.amazon.com/premiumsupport/knowledge-center/ec2-internet-connectivity/

我也有类似的问题。 EC2 确实可以访问 Internet，但无法连接 Ubuntu 存储库：

我之前确实在具有相同 IP 地址的同一个 EC2 中运行了 apt-get update。未对 EC2 进行任何更改或重新启动。突然它停止工作了。
看起来是 EC2 之外的网络/路由问题。
答案 2 :(得分：-1)
我面临着同样的问题。我已经通过更改安全规则来修复它。 只需将设置更改为默认安全规则即可。
就像入站一样，仅配置了8080端口和22端口。删除其余的安全法。
