错误问题一：
默认安装的Debian，选择的apt-get源，默认的security.debian.org在国内会出现无法使用。
类似地址如下：
deb http://security.debian.org/ stable/updates main
deb-src http://security.debian.org/debian/ squeeze main
这个时候，请检查 vim /etc/apt/sources.list 源地址
解决方法：
国内的服务器换一个 apt-get地址atch
国内快速的apt-get地址列表：
# vim /etc/apt/sources.list
#deb cdrom:[Debian GNU/Linux 6.0.5 _Squeeze_ - Official i386 NETINST Binary-1 20120512-20:43]/ squeeze main
deb http://cdn.debian.net/debian/ squeeze main
deb-src http://cdn.debian.net/debian/ squeeze main
# squeeze-updates, previously known as 'volatile'
deb http://cdn.debian.net/debian/ squeeze-updates main
deb-src http://cdn.debian.net/debian/ squeeze-updates main
很快提示
Reading package lists... Done
结束
