我有一台Debian机器（ Linux debian 2.6.32-5-amd64 #1 SMP Fri Feb 15 15:39:52 UTC 2013 x86_64 GNU/Linux ），在一个NAT后面运行一些端口转发的SSH和Web。 我可以访问networking，我也可以做DNS查找罚款。
我的sources.list的内容
deb http://ftp.br.debian.org/debian squeeze main deb-src http://ftp.br.debian.org/debian squeeze main deb http://ftp.br.debian.org/debian squeeze-updates main deb-src http://ftp.br.debian.org/debian squeeze-updates main deb http://security.debian.org/ squeeze/updates main deb-src http://security.debian.org/ squeeze/updates main
当我尝试apt-get更新时，我得到以下内容

它看起来像是镜像服务器或镜像服务器和您的盒子之间的networking连接有一些问题。 请看看下面的Debian Sources Generator来获取适合你的发行版本，版本库和国家的默认源代码。
现在，截至2016年，Debian 6（squeeze）已经推出到EOL（使用寿命结束），用户还需要在正确的档案链接的位置上追加更多的复杂function。 httpredir域没有帮助find这个。 我做了一些挖掘，最后想出了一个模式，帮助我更新Debian 6 docker容器。
# debian 6 - squeeze now relegated to old archive repos RUN echo 'Acquire::Check-Valid-Until "false";' >/etc/apt/apt.conf.d/90ignore-release-date RUN echo "deb http://archive.debian.org/debian-archive/debian squeeze main" > /etc/apt/sources.list RUN echo "deb http://archive.debian.org/debian-archive/debian squeeze-proposed-updates main" >> /etc/apt/sources.list RUN echo "deb http://security.debian.org squeeze/updates main" >> /etc/apt/sources.list RUN echo "deb http://archive.debian.org/debian-archive/debian squeeze-lts main contrib non-free" >> /etc/apt/sources.list
（如果你在shell上input，则删除RUN部分）
Check-Valid-Until标志必须设置为false，因为档案挤压现在发行版超过默认的最大使用期限，否则将不会被加载。 （信贷：海森堡 – https://stackoverflow.com/questions/36080756/archive-repository-for-debian-squeeze ）
