当运行apt-get update后出现如下错误时：
E: Some index files failed to download, they have been ignored, or old ones used instead.
可以将目录下/var/lib/apt/lists/partial/所有的文件清掉，再次运行apt-get update即可！自带源在大陆不好。
出现以下错误：
修改dns:
1,重启生效：
sudo vi /etc/resolvconf/resolv.conf.d/base（这个文件默认是空的）
在里面插入：
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 114.114.114.114
如果有多个DNS就一行一个
修改好保存，然后执行
sudo resolvconf -u
再看/etc/resolv.conf，最下面就多了3行：
cat /etc/resolv.conf
# 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 8.8.8.8
nameserver 8.8.4.4
nameserver 114.114.114.114
可以看到我们的设置已经加上了，然后再ping一个域名，当时就可以解析了，无需重启。
2，重启失效：
配置文件地址 /etc/resolv.conf
使用编辑器打开
改为如下内容：
search localdomain
nameserver 202.96.128.86 希望修改成的DNS
nameserver 202.96.128.166 备用DNS
重启网络：sudo /etc/init.d/networking restart。即可
