Ubuntu22.04.01Desktop桌面版 换apt源为国内源阿里源

备份 /etc/apt/sources.list

### 两位年月日时分秒
sudo cp -a /etc/apt/sources.list /etc/apt/sources.list.$(date "+%y%m%d%H%M%S").bak
### 两位年月日时分秒+纳秒
sudo cp -a /etc/apt/sources.list /etc/apt/sources.list.$(date "+%y%m%d%H%M%S%N").bak
### 年-月-日 时:分:秒 , 因为有空格,又要使用$, 所以要加双引号
sudo cp -a /etc/apt/sources.list "/etc/apt/sources.list.$(date "+%F %T").bak"
### 标准: 年-月-日T时:分:秒 , 因为有空格,又要使用$, 所以要加双引号
sudo cp -a /etc/apt/sources.list "/etc/apt/sources.list.$(date "+%FT%T").bak"

备份的效果

编辑 /etc/apt/sources.list

sudo vi /etc/apt/sources.list

sudo nano /etc/apt/sources.list

sudo gedit /etc/apt/sources.list

原先的内容不用保留, 全部替换为: 👇

阿里源 (18.04是bionic , 20.04是focal , 22.04是jammy)
