Debian更新时候出现“GPG error The following signatures couldn't be verified because the public key is not available”错误

apt-get update时出现错误,如下:

W: GPG error: http://ftp.us.debian.org lenny-proposed-updates Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY AED4B06F473041FA

这个是由于PGP证书的问题,如下解决:

gpg --keyserver wwwkeys.pgp.net --recv-keys AED4B06F473041FA
gpg -a --export AED4B06F473041FA |apt-key add -

OK,重新apt-update,可以了。
