网上搜了文章，换源后还是一样。
具体做法：
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup
sudo vi /etc/apt/sources.list

sudo apt-get update

换163，sohu都一样。

还有安装GD库，一样无法完成。

各位大神过来看看！！

跟源没关系。你服务器上dns没设置对，解析不了地址

DNS改了(很奇怪每次改了重启，又被改成：meserver 8.8.8.8，前面少两个字母，一番折腾改好)，有改善，前面一段都没问题了，如下：

DNS:
/etc/resolv.conf里加：
nameserver 202.101.172.47
nameserver 8.8.8.8

是什么问题？

用：sudo apt-get upgrade已经升级好了。
上述错误仍然在。

GD库也安装好了。

谢谢astolia，谢谢ubuntu，谢谢央视，哈哈哈！

你好 请问现在你能更新14.10 的源吗 我到 http://cn.archive.ubuntu.com/ubuntu/dist 下查看没有发现utopic的内容
