Linux ubuntu 切换阿里更新源

Linux ubuntu 切换阿里更新源

查看codename

首先查看本身的ubuntu系统的codename，直接致使你更新的源是否对你的系统起效果，查看方法： lsb_release -a

benny@benny:/etc/apt$ lsb_release -a 
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04 LTS
Release:	18.04
Codename:	bionic
benny@benny:/etc/apt$

个人系统显示：Codename: bionic

确认阿里源支持

登录如下网页：http://mirrors.aliyun.com/ubuntu/dists/ 该网页显示了阿里云支持的ubuntu系统下各个Codename版本，确保本身的Codename在该网页中存在（通常都会有的）

备份系统源

cd /etc/apt
sudo mv sources.list sources.list_bak

添加新的源文件

sudo vi sources.list

并添加如下内容：注意，每一行的trusty应该用第一步查看获得的Codename来代替

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