晃悠了差不多两个月，突然发现Debian6发布，好消息！！！可是突然发现更新Debian5的时候提示公钥错误，错误提示
W: GPG error: http://mirrors.163.com lenny-proposed-updates Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY AED4B06F473041FA W: GPG error: http://mirrors.163.com lenny/updates Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY AED4B06F473041FA W: You may want to run apt-get update to correct these problems
解决办法参考了http://www.unixaid.info/index.php/unixtecspt/31-botndinst/747-debiannopubkey.html，
可是一直出现
gpg: requesting key 473041FA from hkp server subkeys.pgp.net gpg: keyserver timed out gpg: keyserver receive failed: keyserver error
最终解决办法
aptitude install debian-archive-keyring
最后强烈建议javaeye在代码里面加个命令的选择，不然每次都只能放到html里面
