ubuntu错误解决。

ubuntu中出现如下错误：

W: Failed to fetch http://cn.archive.ubuntu.com/ubuntu/dists/precise-backports/main/i18n/Translation-en  Something wicked happened resolving 'cn.archive.ubuntu.com:http' (-5 - No address associated with hostname)

W: Failed to fetch http://cn.archive.ubuntu.com/ubuntu/dists/precise-backports/multiverse/i18n/Translation-en_US  Something wicked happened resolving 'cn.archive.ubuntu.com:http' (-5 - No address associated with hostname)

W: Failed to fetch http://cn.archive.ubuntu.com/ubuntu/dists/precise-backports/universe/i18n/Translation-en  Something wicked happened resolving 'cn.archive.ubuntu.com:http' (-5 - No address associated with hostname)

E: Some index files failed to download. They have been ignored, or old ones used instead.

解决办法：

在/etc/resolv.conf中加入DNS地址：

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 172.16.10.1
