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：
# https://opsx.alibaba.com/mirror deb https://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb https://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb https://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb https://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb https://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse # 仿照清华镜像源，注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释 # deb-src https://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse # deb-src https://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse # deb-src https://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse # deb-src https://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse # deb-src https://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
Ubuntu 18.04 TLS版本清华镜像源：

4. 刷新列表，一定要执行刷新
sudo apt-get update sudo apt-get upgrade sudo apt-get install build-essential
