问题描述
刚得到一个运行Ubuntu 11.04的新VPS并尝试对其进行更新。我得到这个错误。每当使用apt-get时，我都会收到相同的错误

如果需要，这是我的/etc/apt/sources.list
root@Rx:/etc# more /etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu natty main
deb http://archive.ubuntu.com/ubuntu natty-updates main
deb http://security.ubuntu.com/ubuntu natty-security main
deb http://archive.ubuntu.com/ubuntu natty universe
deb http://archive.ubuntu.com/ubuntu natty-updates universe
如果需要，我进行了ping测试：
root@Rx:~# ping -n 8.8.8.8

这是/etc/resolv.conf

nameserver 199.193.248.1
最佳办法
问题是您原来使用的DNS服务器没有响应您的查询。您可以将另一个添加到列表中进行检查。 8.8.8.8(由Google提供)最容易记住。
将行nameserver 8.8.8.8添加到/etc/resolv.conf中以查询该服务器。
如果原始服务器是VPS提供商提供给您的服务器，则您可能需要与他们的支持团队一起使用-可能有某种管理工具依赖于它。除此之外，您可以永远使用8.8.8.8作为主要DNS。
