        修改 /etc/apt/sources.list 文件，也即修改鏡像源，能夠加快在 Ubuntu 中下載和更新相關軟件數據；否則默認情況下使用的是外網，下載起來比較慢！！！

基本步驟：

1、復制一份 /etc/apt/sources.list 文件，以作備用,其中 sources-bak.list 是備份文件名；

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

2、打開  /etc/apt/sources.list  文件；

 sudo vi /etc/apt/sources.list
  
  
  
          

3、點擊 D 刪除里面的所有內容；

4、打開鏡像源 阿里雲鏡像源鏈接 ；

5、找到 Ubuntu 對應版本的鏡像； 

   
   
   
           
 
            
 
             
 
              
 
             
 
             
 
              

                deb http: 
               //mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse 
              
 
             
 
            
 
             
 
              
 
             
 
             
 
              

                deb-src http: 
               //mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse 
              
 
             
 
            
 
             
 
              
 
             
 
             
 
              
 
              
 
             
 
            
 
             
 
              
 
             
 
             
 
              

                deb http: 
               //mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse 
              
 
             
 
            
 
             
 
              
 
             
 
             
 
              

                deb-src http:

                deb http: 
               //mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse 
              
 
             
 
            
 
             
 
              
 
             
 
             
 
              

                deb-src http:

                deb http: 
               //mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse 
              
 
             
 
            
 
             
 
              
 
             
 
             
 
              

                deb-src http: 
               //mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse

 6、將其內容復制到 /etc/apt/sources.list 文件下；

7、點擊 ESC 然后輸入“：wq”，保存並退出；
