UOS （Ubuntu）系统更换国内源_uos源地址

今天在uos官网上下载UOS服务器版的操作系统，需要更换一下国内的源，下面就和大家一起分享一下。

备份配置文件

sudo cp /etc/apt/sources.list{,.bak}

更还源

## 删除全部内容之后，添加上新的源
vim /etc/apt/sources.list

下面是常用的国内源

1）阿里源：

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse 
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse 
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse 
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse 
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse 
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

2）清华源：

# 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 
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

更新源

• 更新软件列表

sudo apt-get update

• 更新软件（将已安装的软件与刷新的软件列表中的软件版本进行对比，如果发现已安装的软件版本太低，就会提示更新）

sudo apt-get upgrade
