BackBox是基于Ubuntu的Linux发行版，因此，我们可以使用Ubuntu的更新源作为BackBox的更新源。

1.查看系统版本信息：

输入：

uname -a

显示计算机及操作系统的有关信息，在回显里我们可以看到：

Linux master 4.10.0-38-generic #42~16.04.1-Ubuntu SMP Tue Oct 10 16:30:51 UTC 2017 i686 i686 i686 GNU/Linux

这表明我们现在使用的Linux内核是Ubuntu

另外我们还可以通过输入命令：

cat /proc/version

查看内核版本，运行回显如下：

Linux version 4.10.0-38-generic (buildd@lgw01-amd64-020) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4) ) #42~16.04.1-Ubuntu SMP Tue Oct 10 16:30:51 UTC 2017

输入：

cat /etc/issue

可以查看当前使用的发行版的信息，回显如下：

BackBox Linux 5 \n \l

因此，本文的操作环境为：

BackBox 5（基于Ubuntu16.04.1）

当然，在添加更新源时对版本的要求也不是这么绝对，一般情况下，只要更新源本身还在更新并能通过互联网访问，那么更新源就是可以使用的。

2.BackBox 5自带的更新源

BackBox 5自带的更新源均指向Ubuntu的官网地址，自带的更新源如下：

#deb cdrom:[BackBox Linux 5 - Release i386]/ xenial main multiverse restricted universe# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to# newer versions of the distribution.deb http://cn.archive.ubuntu.com/ubuntu/ xenial main restricted# deb-src http://cn.archive.ubuntu.com/ubuntu/ xenial main restricted## Major bug fix updates produced after the final release of the## distribution.deb http://cn.archive.ubuntu.com/ubuntu/ xenial-updates main restricted# deb-src http://cn.archive.ubuntu.com/ubuntu/ xenial-updates main restricted## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu## team.

3.补充BackBox国内更新源：

输入：

sudo leafpad /etc/apt/sources.list

使用leadpad打开更新源配置文件。

也可以输入：

sudo vi /etc/apt/sources.list

使用vi编辑器打开更新源配置文件

注：不要忘记加上sudo

将以下更新源复制到原更新源的前面保存即可：

注：更改更新源之前最好先对原有的更新源做一个备份，备份命令：

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