報(bào)了一堆錯(cuò)誤：
Err http://cn.archive.ubuntu.com trusty InRelease
Err http://cn.archive.ubuntu.com trusty-updates InRelease
Err http://cn.archive.ubuntu.com trusty-backports InRelease

W: Failed to fetch http://cn.archive.ubuntu.com/ubuntu/dists/trusty/InRelease
解決方案： 修改DNS
sudo vi /etc/resolvconf/resolv.conf.d/base
在里面插入：
nameserver 8.8.8.8
nameserver 8.8.4.4
修改好保存!wq，
然后執(zhí)行
$ sudo resolvconf -u
再看 /etc/resolv.conf，最下面就多了2行：
$ cat /etc/resolv.conf
顯示
# 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
此時(shí)執(zhí)行
$ sudo apt-get update
可以運(yùn)行，然后就可以使用sudo apt-get install **指令了。
