刚刚得到一个运行Ubuntu 11.04的新VPS，并试图更新它。 我得到这个错误。 每当使用apt-get时，我都会得到相同的错误

如果需要的话，我做了一个pingtesting：

这是/etc/resolv.conf
root@Rx:~# more /etc/resolv.conf nameserver 199.193.248.1
问题是你最初的DNS服务器没有回应你的查询。 你可以添加另一个到列表来检查。 8.8.8.8（由Google提供）是最容易记住的。
将行nameserver 8.8.8.8添加到/etc/resolv.conf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，那么您可能需要将其与支持团队联系起来 – 可能存在一些依赖于此的pipe理工具。 除此之外，您可以永远使用8.8.8.8作为您的主DNS。
