Linux ubuntu 切換阿里更新源

Linux ubuntu 切換阿里更新源

查看codename

首先查看本身的ubuntu系統的codename，直接致使你更新的源是否對你的系統起效果，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$

個人系統顯示：Codename: bionic

確認阿里源支持

登錄如下網頁：http://mirrors.aliyun.com/ubuntu/dists/ 該網頁顯示了阿里雲支持的ubuntu系統下各個Codename版本，確保本身的Codename在該網頁中存在（通常都會有的）

備份系統源

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

添加新的源文件

sudo vi sources.list

並添加如下內容：注意，每一行的trusty應該用第一步查看獲得的Codename來代替

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