我刚刚在我的服务器上配置了 WKD，并且
gpg -v --auto-key-locate clear,wkd,nodefault --locate-key [email protected]
我的大多数 uid/key 组合都按预期工作，除了一个地址 ([email protected]) 链接到当前和撤销的密钥。上述命令的输出如下所示：
gpg: Note: RFC4880bis features are enabled.
gpg: using pgp trust model
gpg: pub rsa4096/68FD03F8C6AB1DE4 2016-06-15 Old User <[email protected]>
gpg: Note: signature key 68FD03F8C6AB1DE4 expired Mon Jun 14 18:12:44 2021 CEST

即使 [email protected] 是新密钥的主要 uid，gpg 也会显示此密钥的另一个 uid ([email protected])。这很奇怪，但无关紧要。但随后 gpg 继续选择可通过 WKD 以某种方式获得的已撤销密钥。
https://metacode.biz/openpgp/web-key-directory上的 WKD 测试提供了类似的结果，但它显示了当前密钥和撤销密钥的指纹。
两个问题：
- 哪个 WKD 服务器托管我已撤销的密钥，使其优先于我在 domain.com 上的 WKD 服务器？
- 为什么 gpg 会选择过期和撤销的密钥而不是有效密钥？
谢谢，扬
