Linux 更换国内源
作者：互联网
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：我使用的系统是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
