Debain6已经没有更新支持了
#会提示找不到更新源 apt-get update
为了继续按照软件，需要做两件事情：
1、修改/etc/apt/sources.list文件
# deb http://ftp.debian.org/debian/ squeeze-updates main contrib # deb http://http.us.debian.org/debian/ squeeze contrib non-free main # deb-src http://ftp.debian.org/debian/ squeeze-updates main contrib deb http://archive.debian.org/debian squeeze main deb http://archive.debian.org/debian squeeze-lts main
2、增加/etc/apt/apt.conf文件
