debian的gpg校验问题

刚刚买了个vps，debian 64bit的系统，用系统默认的source报错误：

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

 

网上多是使用wwwkeys.eu.pgp.net服务器取gpg，我的vps总是timeout，换了个服务器，ok了！

过程如下：

1、下载密钥

luan78zao:~# gpg --keyserver subkeys.pgp.net --recv-keys AED4B06F473041FA   gpg: /root/.gnupg/trustdb.gpg: trustdb created gpg: key 473041FA: public key "Debian Archive Automatic Signing Key (6.0/squeeze) " imported gpg: no ultimately trusted keys found gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1)

2、导入密钥

luan78zao:~# apt-key add .gnupg/pubring.gpg   OK

3、apt更新

luan78zao:~# aptitude update   Hit http://mirrors.163.com lenny Release.gpg Get:1 http://mirrors.163.com lenny-proposed-updates Release.gpg [835B] Get:2 http://mirrors.163.com lenny/updates Release.gpg [835B] Hit http://mirrors.163.com lenny Release Hit http://mirrors.163.com lenny-proposed-updates Release Hit http://mirrors.163.com lenny/updates Release Ign http://mirrors.163.com lenny/main Packages/DiffIndex Ign http://mirrors.163.com lenny/non-free Packages/DiffIndex Ign http://mirrors.163.com lenny/contrib Packages/DiffIndex Ign http://mirrors.163.com lenny/main Sources/DiffIndex Ign http://mirrors.163.com lenny/non-free Sources/DiffIndex Ign http://mirrors.163.com lenny/contrib Sources/DiffIndex Hit http://mirrors.163.com lenny-proposed-updates/main Packages/DiffIndex Hit http://mirrors.163.com lenny-proposed-updates/contrib Packages/DiffIndex Hit http://mirrors.163.com lenny-proposed-updates/non-free Packages/DiffIndex Hit http://mirrors.163.com lenny-proposed-updates/main Sources/DiffIndex Hit http://mirrors.163.com lenny-proposed-updates/contrib Sources/DiffIndex Hit http://mirrors.163.com lenny-proposed-updates/non-free Sources/DiffIndex Ign http://mirrors.163.com lenny/updates/main Packages/DiffIndex Ign http://mirrors.163.com lenny/updates/contrib Packages/DiffIndex Ign http://mirrors.163.com lenny/updates/non-free Packages/DiffIndex Ign http://mirrors.163.com lenny/updates/main Sources/DiffIndex Ign http://mirrors.163.com lenny/updates/contrib Sources/DiffIndex Ign http://mirrors.163.com lenny/updates/non-free Sources/DiffIndex Hit http://mirrors.163.com lenny/main Packages Hit http://mirrors.163.com lenny/non-free Packages Hit http://mirrors.163.com lenny/contrib Packages Hit http://mirrors.163.com lenny/main Sources Hit http://mirrors.163.com lenny/non-free Sources Hit http://mirrors.163.com lenny/contrib Sources Hit http://mirrors.163.com lenny/updates/main Packages Hit http://mirrors.163.com lenny/updates/contrib Packages Hit http://mirrors.163.com lenny/updates/non-free Packages Hit http://mirrors.163.com lenny/updates/main Sources Hit http://mirrors.163.com lenny/updates/contrib Sources Hit http://mirrors.163.com lenny/updates/non-free Sources Fetched 1670B in 5s (314B/s) Reading package lists...
