root@ubuntu:~# dpkg-scanpackages radxa /dev/null | gzip >radxa/Packages.gz
root@ubuntu:~# ls
radxa如上radxa为当前目录下哪个文件下存放的deb包,|之后是将scan的结果打包存放到radxa目录下，保存为文件Packages.gz。
修改更新源文件
vim /etc/apt/sources.list
#内如如下
deb file:/// radxa/
file:// 本地文件系统
/ 根目录
radxa/ 根目录下的radxa目录
如果之前的打包文件路径不便，文件修改可如下：
deb file:/// root/radxa/
