大家好！
我两周前从http://cdimage.debian.org/cdimage/weekly-builds/i386/iso-cd/下载了19th
March 2007的testing安装cd，安装的系统
我的sources.list是
deb http://debian.ustc.edu.cn/debian testing main non-free contrib
deb-src http://debian.ustc.edu.cn/debian testing main non-free contrib
deb http://debian.ustc.edu.cn/debian-security testing/updates main
deb http://debian.ustc.edu.cn/debian-uo sid marillat ustc rareware misc
昨天运行aptitude update 和aptitude upgrade后，再次运行aptitude update出现如下错误

signatures couldn't be verified because the public key is not
available: NO_PUBKEY D4F3554EF747D1A0
W: You may want to run apt-get update to correct these problems
这个PUBKEY可能是新的，google没有搜到这个PUBKEY的相关信息，安装了debian-keyring依然有警告。请教有什么办法去掉这个警告，还是就等着更新呢？谢谢！
祝好！
