1.查看Ubuntu版本:

sudo lsb_release -a

顯示結(jié)果如下：

2.備份系統(tǒng)鏡像源文件

備份配置文件，當(dāng)配置出錯(cuò)時(shí)，可以回滾，ubuntu鏡像配置文件是：/etc/apt/sources.list，執(zhí)行下面命令進(jìn)行備份。

cp /etc/apt/sources.list /etc/apt/sources.list.back

3.使用vi修改 sources.list 文件

sudo vi /etc/apt/sources.list

使用命令：:%d 清空文件所有內(nèi)容

復(fù)制下面的源鏡像到文件中，選擇其中一個(gè)源鏡像或者將三個(gè)鏡像源都復(fù)制進(jìn)去sources.list文件中。
