Ubuntu学习笔记——更新源

源就是一些站点,即在源里存放着各种软件包和更新文件的服务器,要安装或更新软件时,就会连接官方源进行数据交互。

在Ubuntu的/etc/apt/sources.list里的就是源的信息,更新源就是更新里面的内容,之所以要更新源是因为Ubuntu本身的源慢且会出现错误,换成镜像源可以提高速度和稳点性。

具体操作如下:

  1. 先将源的文件备份
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

              (cp命令是拷贝的意思,cp 源文件 目标文件)

     2.用gedit命令打开sources文件并编辑

sudo gedit sources.list

     3.在打开的文件中粘贴你需要的源(在后文)

      4.更新

sudo apt-get update
sudo apt-get upgrade

       (先更新,后升级)
