There is no public key available for the following key IDs 问题

OS: debian 4.0 etch
此问题比较普遍故记录之且供参考
一般都是在apt-get update 后出错：

W: There is no public key available for the following key IDs:
9AA38DCD55BE302B
W: You may want to run apt-get update to correct these problems

按照提示运行apt-get update这个指令很遗憾无论运行多少次都无济于事

为演示这一过程先下apt-key指令 import当前的keys
# apt-key update

gpg: key 2D230C5F: "Debian Archive Automatic Signing Key (2006) " not changed
gpg: key 6070D3A1: "Debian Archive Automatic Signing Key (4.0/etch) " not changed
gpg: key ADB11277: "Etch Stable Release Key " not changed
gpg: key BBE55AB3: "Debian-Volatile Archive Automatic Signing Key (4.0/etch)" not changed
gpg: Total number processed: 4
gpg: unchanged: 4

当前系统有4个keys

增加上面列出的key
gpg --keyserver wwwkeys.eu.pgp.net --recv-keys  9AA38DCD55BE302B && apt-key add /root/.gnupg/pubring.gpg

再来看看系统中的trusted gpg keys信息
# apt-key list
/etc/apt/trusted.gpg
--------------------
pub   1024D/2D230C5F 2006-01-03 [expired: 2007-02-07]

pub   4096R/55BE302B 2009-01-27 [expires: 2012-12-31]
uid                  Debian Archive Automatic Signing Key (5.0/lenny)

OK 5个最后一行正是刚才加入的
再次apt-get update 就应该没有问题了

#apt-get update

Get:1 http://security.debian.org etch/updates Release.gpg [1032B]

还有一种情况就是 key过期的问题那么这时候可以一个个先删除系统中的key
比如
apt-key list
apt-key del 55BE302B
apt-key del BBE55AB3
...
然后删除debian-archive-keyring包
dpkg –purge debian-archive-keyring
再次重新安装
apt-get install debian-archive-keyring
基本上都能解决这个问题
