Ubuntu配置apt安裝源為清華源[含自動配置腳本]

一、備份原配置文件

Ubuntu 的軟件源配置文件是/etc/apt/sources.list。將系統自帶的該文件做個備份，以防萬一。

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

二、修改sources.list文件

我習慣與使用vim編輯文件，如果你沒有安裝可以執行命令sudo apt-get install vim安裝。

選擇你系統對應版本，下面的就是需要你添加到sources.list文件中的內容。

使用sudo vim /etc/apt/source.list打開文件，將文件原內容刪除，添加在清華源獲取的內容，保存。

三、更新軟件列表和軟件源

sudo apt-get update
sudo apt-get upgrade

四、 其他幾個國內的軟件源

4.1 中國科技大學軟件源

五、腳本一鍵配置apt源

示例為ubuntu18.04配置清華鏡像源,其他版本或者其他源，做對應替換即可。

#!/bin/bash
#更新apt源為清華源
echo "[Info] 正在備份默認apt源..."
cp /etc/apt/sources.list /etc/apt/sources.list.bak
echo "[Info] 正在替換apt源為清華apt源..."
echo deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse > /etc/apt/sources.list
echo deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse >> /etc/apt/sources.list
echo deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse >> /etc/apt/sources.list
echo deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse >> /etc/apt/sources.list
echo "[Info] 正在更新源..."
apt update
echo "[Info] 正在更新軟件..."
apt upgrade -y
