Ubuntu快速换源教程
目的:为了解决上网查资料过慢问题。可以通过换源来提高速度。
(1)备份系统源
cd /etc/apt
sudo mv sources.list sources.list.bak
(2)开始修改sources文件
有安装vim用户:
sudo vim sources.list
无安装vim用户:
sudo gedit sources.list
(3)写入阿里云的源(版本:Ubuntu 22.04)
发现现在很多源都没办法用了,我自己用了阿里云的源可以用,希望对你们有用
deb http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse
阿里云的源(版本:Ubuntu 21.04)
deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
!注意查看自己Ubuntu版本,如果依赖比你系统版本新,那么它会更新你系统的版本库。特别是一些基础库,如libc等。这些请大家一定要看清楚看清楚看清楚再更新。因为一旦更新后,你的系统内核可能就不稳定,常见的就是桌面崩了。
可以用此指令查看Ubuntu版本:
lsb_release -a
显示如下:
Distributor ID: Ubuntu //类别是ubuntu Description: Ubuntu 14.04.2 LTS //14年2月4月发布的稳定版本,LTS是Long Term Support:长时间支持版本 三年 ,一般是18个月 Release: 14.04 //发行日期或者是发行版本号 Codename: trusty //ubuntu的代号名称
(4)执行更新
sudo apt-get update
