我已将我的 GPG 密钥从一台服务器复制到另一台服务器，在第一台服务器上一切正常，在新服务器上我得到以下内容：（我已包含 list-keys 和 list-secret-keys 的输出
[www@localhost data]$ gpg escs_hr_feed.pgp
You need a passphrase to unlock the secret key for
user: "Encrypt <[email protected]>"
2048-bit RSA key, ID 8E7BFE3A, created 2015-06-24 (main key ID B943D3E2)
gpg: cancelled by user
gpg: encrypted with 2048-bit RSA key, ID 8E7BFE3A, created 2015-06-24

答案1
所以问题竟然是，如果你sudo su -给了用户，就不能使用gpg，需要直接以用户身份登录。
（至少在我公司的服务器设置上）
