挂载本地硬盘的ISO镜像文件

1.定位Debian ISO镜像的位置，比如说sda3

fdisk -l

2.挂载：

# mount -t auto /dev/sda3 /media/mnt

生成isodebian路径 /mnt# mkdir isodebian

t# mount -o loop /media/mnt/debian-8.4.0-amd64-DVD-1.iso /mnt/isodebian
mount: /dev/loop0 is write-protected, mounting read-only

3.添加本地源 

/etc/apt# vi sources.list

deb http://ftp.cn.debian.org/debian/ jessie main contrib
deb-src http://ftp.cn.debian.org/debian/ jessie main contrib
deb file:///mnt/isodebian jessie main contrib

 4. 验证更新

#apt-get update
