无法从 EC2 实例执行 sudo apt-get update

问题描述 投票：0回答：10

我无法通过 Ubuntu EC2 实例执行 sudo apt-get update。 当我跑步时 -

sudo apt-get update

我收到以下错误：-

为了解决这个问题，我遵循了this并执行了以下操作-

sudo sed -i 's/eu-central-1\.ec2\.//g' /etc/apt/sources.list

我重新启动了系统并再次尝试。现在我在执行 sudo apt-get update 时遇到此错误 -

我遇到了同样的问题，为了解决它，我必须向所有流量添加另一个出站规则并将目的地设置为

anywhere
。

听起来您的实例没有互联网访问权限。

您的实例需要位于公有子网中，并具有指向附加 Internet 网关的路由表：https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Internet_Gateway.html

或者您的实例位于私有子网中，需要一个到 nat 网关的路由表：https://aws.amazon.com/premiumsupport/knowledge-center/ec2-internet-connectivity/

编辑：如果您已确认上述内容已到位，请检查出站安全组规则是否允许在预期端口上进行传出互联网访问。

假设您的 ec2 位于公共子网中，并附加了 nat 网关。根据错误消息，需要安全组出站 http 端口 80 规则。希望这有帮助

噢，你的 ec2 实例需要 vpc 和子网，你可以从 aws vpc 管理中检查这些 https://ap-south-1.console.aws.amazon.com/vpc/home?region=ap-south-1 #子网： 或者如果您需要指导，请使用 https://docs.aws.amazon.com/batch/latest/userguide/create-public-private-vpc.html

如果您已经尝试了发布的所有解决方案，然后更改区域，它将起作用，我在两个不同的区域中执行了完全相同的步骤，并且它在一个区域中起作用，而另一个区域则不起作用，这个问题面临很多人。

我建议查看安全配置，即安全组和子网 NACL。这些是超时和无法解释的连接问题的常见嫌疑 - 特别是如果它们尚未配置或评估。

对于安全组，因为没有到 EC2 实例的传入连接，因此在更新存储库和服务器之间创建有状态连接。这意味着我们需要向实例的安全组显式添加出站规则。这可以是一般规则（出站到任何地方：0.0.0.0/0 或 ::0），也可以是针对预期 IP 集的显式规则。

对于 NACL，确保允许流量流向 NACL 和流量将流经的子网的任何地方。再说一遍，这可能是一般规则（从实例入站，出站到任何地方），或者是针对预期 IP 集的显式规则。

好吧，非常确定您的 nat 网关存在一些问题。从概念上讲，如果您要去，那么您的计算机现在位于私有子网中，并且要与外界通信，它需要通过 nat 网关与互联网网关通信，所以这就是问题。您的 nat 网关无法从互联网网关访问互联网。因此解决方案是您只需删除您的 nat 网关并重新创建它，并在创建时将其连接到公共子网。下一步是转到路由表并将其附加到私有路由表 -> 编辑路由 -> 和 0.0.0.0/0（允许来自任何地方的请求）并在下拉列表中选择 nat 网关，它将自动显示您创建的 nat 网关 -> 单击保存更改。您完成后只需重新启动计算机运行命令 sudo apt-get update。

我也有类似的问题。 EC2确实可以访问互联网，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 EC2 内运行过 

apt-get update
。未对 EC2 进行任何更改或重新启动。突然就停止工作了。

看起来 EC2 外部存在网络/路由问题。

从本地系统停止或删除防病毒软件并停止防火墙。重新处理安装。现在效果很好。

我也面临着同样的问题。我已经通过更改安全规则修复了这个问题。 只需将您的设置更改为默认安全规则即可。

与入站一样，仅配置了 8080 端口和 22 端口。删除其余的安全法。
