ubuntu 14.10源推荐-apt-get

直接来清华官方这里取（随时更新）

直接来阿里云找你想要（随时更新）

最近虚拟技上安装软件都是local错误之类，采用apt-get update 更新都是404，
apt-get update Sources 404 Not Found [IP:xx.xx]之类
搜索了下可能是源的问题
先看下版本

cat /etc/issue

Ubuntu 14.10 \n \l

备份下
cp /etc/apt/sources.list /etc/apt/sources.list-bak

添加新的源头到sources.list文件
sudo vim /etc/apt/sources.list

sudo apt-update

完毕！
经本人测试，上面用的是香港中文大学的，用了163和aliyun的还是404.
