Ubuntu18 将系统默认源更改为阿里源

ubuntu默认使用的国外的源，在更新的时候会很慢，可以使用国内的阿里的源,那效率和速度,你知道的~

 

1.先备份文件

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

2.清空

sudo > /etc/apt/sources.list

3.写入

sudo vim /etc/apt/sources.list

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

备注:    如果报错 command not found ,说明没有安装vim编辑器,使用命令：sudo apt-get install vim 安装即可

4.更新

sudo apt-get update&&sudo apt-get upgrade&&sudo apt-get install -f
