Ubuntu18.04 下改apt源為阿裡雲源

1、備份原有apt源檔案

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

2、檢視系統版本代号

lsb_release -c
           

3、修改系統的sources.list檔案

sudo vim /etc/apt/sources.list
           

添加一下内容到檔案最前面

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
