一：问题概述
ubuntu，我们在使用apt新装软件的时候，会使用官方的网站去下载软件，但是会因为国内的转接点太多，而导致下载的速度非常慢 ，我们可以通过换成一些中间的节点来进行下载，比如阿里源，中科大源，清华源等等，这样的网站，他们会定时和官方的源进行同步和更新，而我们直接同步他们，速度就会比直接同步官方的源快很多，这样能够大大增加我们的下载软件的速度。
二：ubuntu系统更换源
更换源的方法非常简单:修改/etc/apt/sources.list文件即可
2.1：进入/etc/apt/
cd /etc/apt
2.2：修改sources.list文件
sudo vi sources.list (要有管理员权限)
2.3：可以在修改前先对 sources.list文件进行备份
sudo cp sources.list sources.list.bak
2.4:删除掉sources.list的其他内容，任意选择一种源的内容复制粘贴进去，保存，例如，选择阿里源
2.5:更新apt
sudo apt-get update

查询Linux某命令来自哪个包
Debian：（Ubuntu等）
先安装apt-file
sudo apt-get install -y apt-file
apt-file update
查询命令：(已查询ifconfig为例)
root@debian ~ # apt-file search bin/ifconfig
net-tools: /bin/ifconfig
apt-file search -x(--regexp) 后可接正则表达式，如：
root@deepin ~ # apt-file search -x 'bin/rz$'
lrzsz: /usr/bin/rz
root@deepin ~ # apt-file search --regexp 'bin/rz$'
lrzsz: /usr/bin/rz
CentOS：
root@CentOS7 ~ # yum provides *bin/ifconfig
