关于初次使用ubuntu的相关记录

初次接触ubuntu的时候啥也不知道，所以总是什么都是一塌糊涂，现在随笔记录下工作当中遇到的关于ubuntu的问题，因为本人在做开发的时候用到了ubuntu，所以硬着头皮高ubuntu，下面就简单的说一下关于ubuntu的源更新问题。
1、ubuntu系统为什么要更新源：
ubuntu在做发行版本的时候并不是测试所有的免费软件，所以在它的更新源里没不是包括所有的软件链接，假如你想要获得ubuntu系统里没有默认包含的软件，你就得自己动手更新软件源。另一种情况就是ubuntu对一些已经包含的软件有一个定期更新过程，所以也需要更表软件源
2、在ubuntu系统安装完成后应该第一件事就是及时的更新源。
3、如何给ubuntu系统手动更新源
找到etc/apt/sources.list，在更改这个文件之前应该先将该文件备份，cp -p -i sources.list  sources.list.bk
在家目录执行sudo gedit /etc/apt/sources.list 打开这个文件后将下面的更新源列表加入到该文件中
将更新源替代原来源，保存即可
