Ubuntu安裝完畢之后，默認的源是Ubuntu自己的，但畢竟Ubuntu服務器在國外，我們訪問起來會比較慢，可以將軟件源切換為國內源，比如：阿里源，清華源，中科大源等等。在這邊以清華源為例，其它源也是一樣的道理。

1 切換源之前先把配置文件備份一份：

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

2 找到清華源官網：

清華源官網

一定要選擇與自己版本相對應的源，比如當前使用Ubuntu20.04，最好使用此版本的源，否則有可能會有意料不到的問題，良許就吃過這方面的虧。

網絡上也有很多教你換源的帖子，但都是直接給出內容，有可能源與自己的版本不一致，所以最好自己去官網復制。

3.將之前的源全部刪除

echo ” > sources.list

4.編輯新源文件

nano sources.list

5.加入新的數據源（清華數據源）

# 默認注釋了源碼鏡像以提高 apt update 速度，如有需要可自行取消注釋 deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse# 預發布軟件源，不建議啟用 # deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse

6.使用新源替換掉原來的源（一定要加sudo）：

sudo vi /etc/apt/sources.list

7.然后更新軟件包緩存：

sudo apt update

這個命令，會訪問源列表里的每個網址，并讀取軟件列表，然后保存在本地電腦。

8.通常我們會緊跟著再執行命令：

sudo apt-get upgrade

這個命令，會把本地已安裝的軟件，與剛下載的軟件列表里對應軟件進行對比，如果發現已安裝的軟件版本太低，就會提示你更新。

9.備用數據源【阿里】
