您必须在公共密钥服务器上搜索给定的密钥ID:在您的情况下,ID C3C45C06
将找到的密钥导入本地密钥库中,然后验证就可以了。我使用Ubuntu 12.04,它随附Seahorse密钥管理软件。在导入密钥之前,我看到了以下内容:
~/Downloads$ gpg --verify --keyring ./gnu-keyring.gpg icecat-31.5.0.en-US.linux-x86_64.tar.bz2.sig icecat-31.5.0.en-US.linux-x86_64.tar.bz2
gpg: Signature made 9.03.2015 (пн) 22,35,52 EET using RSA key ID D7E04784
gpg: Can't check signature: public key not found
导入密钥后,我看到了:
~/Downloads$ gpg --verify --keyring ./gnu-keyring.gpg icecat-31.5.0.en-US.linux-x86_64.tar.bz2.sig icecat-31.5.0.en-US.linux-x86_64.tar.bz2
gpg: Signature made 9.03.2015 (пн) 22,35,52 EET using RSA key ID D7E04784
gpg: Good signature from "Ruben Rodriguez (GNU IceCat releases key) <ruben@gnu.org>"
