Linux 更换国内源

本文主要是介绍Linux 更换国内源,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

 1.事件背景

  事情起因是因为我想安装xvfb,执行sudo apt-get install xvfb发现安装报错,看报错原因是被墙导致,因为我用的默认源也没有挂代理;然后就百度,发现都是互相抄,什么换阿里源啊,163源、中科源之类,我都试过,并且发现这些源在更新过程会有一些错误或者更新被忽略,导致我再次执行sudo apt-get install -y xvfb报错说未找到包。

  我就接着百度,然后有一条评论给了我灵感,既然默认源切换国区可以安装包,那么我把默认域名us.ports.ubuntu.com换成国内的,us代表美国,zh代表中国,我就试了zh.ports.ubuntu.com,发现真的可以!

2. 替换方法

Ps:我使用的系统Ubuntu 18.04 LTS

1.先对默认源进行备份

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

2.进入默认源编辑

sudo vi /etc/apt/sources.list

3.全局替换

 3.1 按ESC键输入:
 3.2 粘贴下面批量替换命令

%s/us\./zh\./g

4. 保存后再执行更新源命令

 

执行完上述操作步骤后再输入你想安装的包,会发现可以安装了!

 

最后我想吐槽那些原封不动的抄袭者,虽然转载他人文章可以备份,但是当某一天你想上网查找一个问题的解决方法时,发现全网都是同一个答案,还是一模一样的,而想要找到真正有用的答案无异于海底捞针!

 

3. 完整源文件备份

默认源文件
