这是我的/etc/apt/sources.list
###### Debian Main Repos deb http://ftp.us.debian.org/debian/ lenny main contrib non-free ###### Debian Update Repos deb http://security.debian.org/ lenny/updates main contrib non-free deb http://ftp.us.debian.org/debian/ lenny-proposed-updates main contrib non-free
当我这样做时：
# apt-get update
我得到一些好的线，然后：

从一个小小的捅过来看，Debian镜像似乎是个问题。 根据镜像信息，lenny应该是可用的，尽pipe您可能需要在/etc/apt/sources.list中将“lenny”的每个实例更改为“oldstable”。 然而，拉起3面镜子，都显示“lenny”和“oldstable”不再列出。
更新：我做了一些更多的探索，发现USC Mirror看起来仍然有“lenny”列出。 注释掉你在sources.list的现有条目并复制它们：
deb http://ftp.us.debian.org/debian/
replace为：
deb ftp://mirrors.usc.edu/pub/linux/distributions/debian/
看看这是否有窍门。
幸运的是，这只是一个暂时的问题，几天后就会自行解决。
更新2：看起来这不是临时的， http://archive.debian.org是为Lenny提供包的最好的地方。 此外，Lenny在2012年2月12日的安全支持似乎已经结束，尽pipe他们在2012年3月10日发布了5.0.10版本的更新。
这可能是值得计划升级，尤其是对任何互联网/面向公众的服务器。
修改你的/etc/apt/sources.list如下：
deb http://archive.debian.org/debian/ lenny main contrib non-free deb-src http://archive.debian.org/debian/ lenny main contrib non-free deb http://archive.debian.org/debian-security lenny/updates main contrib non-free deb-src http://archive.debian.org/debian-security lenny/updates main contrib non-free deb http://archive.debian.org/debian-volatile lenny/volatile main contrib non-free deb-src http://archive.debian.org/debian-volatile lenny/volatile main contrib non-free
Lenny软件包已从所有镜像中移除到：archive.debian.org因此，请将您的sources.list更新为：deb http://archive.debian.org lenny main contrib
好的 – 那不是为我工作的，但是
deb http://archive.debian.org/debian lenny main contrib
