| 1. 备份源列表
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。 # 首先备份源列表sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup 2. 打开sources.list文件修改
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）： sudo vim /etc/apt/sources.list 3. 阿里云镜像源-清华镜像源
注意根据具体使用的Ubuntu的版本不同，将文本中trusty替换为下面对应版本的字符串: | 版本 | 版本号 | 代号 | | Lucid(10.04) | 10.04 | lucid | | Precise(12.04): precise | 12.04 | precise | | Trusty(14.04): trusty | 14.04 | trusty | | Utopic(14.10): utopic | 14.10 | utopic | | Ubuntu 16.04 TLS： xenial | 16.04 | xenial | | Ubuntu 18.04 TLS： bionic | 18.04 | bionic | Ubuntu 18.04 TLS版本阿里云镜像源：
