Ubuntu是國外的網站，我們下載東西會非常的慢，這時我們需要更新源，更新成國內的，下載速度就蠻快的了

目錄

• 1.輸入命令修改sources.list文件，當然需要超級權限，所以要加sudo
• 2.編輯/etc/apt/sources.list文件
• 3.更新源
• 4.更新成功
• 附上源地址

1.輸入命令修改sources.list文件，當然需要超級權限，所以要加sudo

sudo vim /etc/apt/sources.list

• 1

如果第一次安裝Ubuntu還沒有更新vim建議使用gedit修改

sudo gedit /etc/apt/sources.list

• 1
• 2

注意：最好備份一下這個文件，免得出錯了回不去了

2.編輯/etc/apt/sources.list文件

在下面隨便挑選一個下載源（博文最后列出，可直接復制）就可以了，這里以阿里源為例

vim版：

gedit版（記得點擊save哦）：

3.更新源

sudo apt-get update

• 1

4.更新成功

附上源地址
