我在Windows 7主机上有一个Debian（VirtualBox）来宾。
我正在尝试安装客户添加，我做了以下步骤。
- “apt-get update”
- “apt-get升级”
- “apt-get install build-essential模块助手”
- “马准备”
- “mount / media / cdrom0”
- “cd / media / cdrom0”
“sh VBoxLinuxAdditions.run”
步骤7无法使用以下消息安装guest虚拟机添加：
=============================================
root@vig-debian:/media/cdrom0# sh VBoxLinuxAdditions.run
