Ubuntu 服务器更新问题

我正在运行 Ubuntu 服务器 (x86)，最近我注意到“sudo apt-get *”停止工作。例如，如果我尝试运行“sudo apt-get update”，它会返回：

起初这看起来像是一个 DNS 问题，但我可以毫无问题地 ping “archive.ubuntu.com”。

PING archive.ubuntu.com (91.189.88.46) 56(84) bytes of data.
64 bytes from lithium.canonical.com (91.189.88.46): icmp_seq=1 ttl=45 time=123 ms
64 bytes from lithium.canonical.com (91.189.88.46): icmp_seq=2 ttl=45 time=124 ms
64 bytes from lithium.canonical.com (91.189.88.46): icmp_seq=3 ttl=45 time=158 ms

对于这个问题或者如何解决它有什么想法吗？

答案1

听起来这可能是代理问题。您是否设置了 HTTP_PROXY 环境变量，或者您是否在 /etc/apt/* 文件中设置了任何“代理”设置（检查 /etc/apt/apt.conf.d/）？

答案2

以下命令的输出是什么？

dig archive.ubuntu.com

curl 'http://archive.ubuntu.com/'

cat /etc/resolv.conf

另外，如果以 root 身份运行这些命令，结果会有什么不同吗？（即sudo dig archive.ubuntu.com？

答案3

尝试将 URL 更改为http://us.archive.ubuntu.com在 /etc/apt/sources.list 中。来自南非http://archive.ubuntu.com解析到与您需要使用的服务器不同的服务器。但是http://us.archive.ubuntu.com确实解析为 91.189.88.46。

在 /etc/resolv.conf 中使用不同的 DNS 服务器也可以解决该问题。

我无法“curl”任何东西，因为它没有安装（&我无法安装它因为apt-get不工作:-/）此时我正在考虑重新安装该操作系统，无论如何我们都在考虑迁移到OpenSolaris。
