docker - 来自kubernetes集群的apt更新给出错误Clearsigned文件无效，得到 'NOSPLIT'(网络需要身份验证吗？)

Question

我部署了一个kubernetes集群，并尝试使用一个简单的bash pod对其进行测试，如下所示

kubectl运行my-shell --rm -i --tty --image ubuntu-bash

在收到shell提示后，我尝试进行apt-get更新并遇到以下错误

root@my-shell-796b6f7d5b-274q9:/# apt-get update
Get:1 http://security.ubuntu.com/ubuntu bionic-security InRelease
Get:2 http://archive.ubuntu.com/ubuntu bionic InRelease

  Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)

Reading package lists... Done

感谢您是否可以提出错误的建议。我觉得这是DNS错误或类似的错误。我已经在shell pod中将nameserver添加为8.8.8.8

Answer 1

似乎代理或防火墙阻止了连接。

该命令在托管Kubernetes的机器上是否有效？

如果是这样，那么Kubernetes就会干扰http://*.ubuntu.com/

如果不是，则说明您当前的网络存在问题
