解读Ubuntu的sources.list 和soucres.litsd

使用过Ubuntu的道友们都知道，默认地址是乌班图的org 配置的，对于国内长途跋涉的各位高手来讲真是艰辛；

所以我们一般在安装的时候会先修改服务器源地址使用国内的比如ali，清华或者华为的

源文件地址默认在  /etc/apt/sources.list，当然如果你安装第三方的一般我们喜欢在/etc/apt下建立一个sources.list.d 目录下再在它下面新建一个xxx.list 来存放第三方的安装的deb地址：

比如第三方谷歌浏览器deb的：

如果你嫌弃麻烦直接手动下载一个xxx.deb谁用dpkg  -i   xxx.deb 进行创建他会帮你创建sources.list.d 以及对应的.list   dpkg  默认是没有的apt-get   自己装个

下面来介绍配置aliyun 的·服务器源：

vim  /etc/apt/sources.list

删除所有的地址:粘贴如下：地址百度的，可以自己找，也可以用我的当然我也是百度的，谁没事背这玩意：

####阿里源地址
# 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，这个是源码安装的
# 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

###清华大学源
# 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

　最后执行热更新就可以了：

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential
