修改ubuntu 18.04的sources.list源为阿里或清华镜像的方法（修改Ubuntu启动顺序）

修改ubuntu 18.04的sources.list源为阿里或清华镜像的方法（修改Ubuntu启动顺序）

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

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：

# https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/ # 默认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 https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse # 预发布软件源，不建议启用 # deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse

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
