如何修改Ubuntu的源列表

Answer 1

简介
Ubuntu缺省的配置的源并不是国内的服务器，下载更新软件都比较慢，本文介绍如何设置源列表，选择比较快的源以节省下载时间。

配置步骤
1. 备份源列表sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup
2. 选择合适的源，替换原文件的内容，保存编辑好的文件以阿里云更新服务器为例（从实际测试上结果分析，个人认为阿里云比网易和搜狐的服务器要快）：deb http://mirrors.aliyun.com/ubuntu/ XXXXX main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ XXXXX-security main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ XXXXX-updates main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ XXXXX-proposed main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ XXXXX-backports main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ XXXXX main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ XXXXX-security main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ XXXXX-updates main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ XXXXX-proposed main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ XXXXX-backports main restricted universe multiverse
根据具体使用的Ubuntu的版本不同，将上述文本中XXXXX替换为下面对应版本的字符串:Utopic(14.10): utopic
Trusty(14.04): trusty
Precise(12.04): precise
Lucid(10.04): lucid
3. 刷新列表sudo apt-get update
更新完毕后，再次安装源时，将从新服务器上下载源包。
