Debian 安装源配置

所有的Linux安装完后第一件事，就是要更新安装源

安装源是什么呢，安装源又称软件源，是指把软件的安装源地址放在一个pool里面,用一条命令（比如apt-get install XXX）就可以按照顺序从源内指定的服务器查询下载并进行更新或安装

源列表文件通常在/etc/apt/sources.list，里面记录了你所用的源服务器地址

0x01 首先我们需要获取root用户，切换权限

su
# 输入你的root账户密码，这里光标不会有显示是否输入，按就完了，注意小键盘及大小写

0x02 切换到root账户后

vi etc\apt\source.list
# vim打开安装源列表文件并进行相应编辑

0x03 vim编辑

1. 方向键移动光标，按i进入插入模式

   注：命令模式下dd为删除本行，x为删除当前字符，输入模式下方向键及delete、backspace均失效。按ESC可退出输入模式,如对当前输入不满意，想要重新输入可以进入命令模式下输入q！。再次进入list文件修改时，会有提示，不要按enter进入继续编辑，按其他任意键，丢弃上次编辑结果以重新进行编辑

2. 将下列复制并替换到list文件内，终端内粘贴快捷键为Ctrl+Shift+V。

3. 光盘文件源于源代码已经注释掉了，如有需要删除前方#即可。注意下列源内包括两种不同的Debian发行版，可注释掉不需要的版本。

4. 修改完成后，进入命令模式，输入:wq!即可（注意:!)

0x04 更新软件源

注意上面的源内包括两种不同的Debian发行版，注释掉不需要的版本，否则这里会有冲突报错，如不在意报错可不注释，目前未发现影响，后续如发现将进行补充，当然大佬们也可以提前帮助指正

sudo apt-get update
sudo apt-get upgrade

等待跑完即可
