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/multiverse/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/restricted/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/restricted/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/universe/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
