Hi,

I just configured WKD on my server, and

gpg -v --auto-key-locate clear,wkd,nodefault --locate-key [email protected]

works as expected for most of my uid/key combos, except for one address
([email protected]) which is linked to both a current and a revoked
key. The output of the above command looks like this:

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
gpg: key 68FD03F8C6AB1DE4: "Old Nickname <[email protected]>" not changed
gpg: pub  ed25519/7CD4656792B3A1F9 2022-06-06  Old User <[email protected]>
gpg: key 7CD4656792B3A1F9: "Old User <[email protected]>" not changed
gpg: Total number processed: 2
gpg:              unchanged: 2
gpg: auto-key-locate found fingerprint xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
gpg: Note: signature key 68FD03F8C6AB1DE4 expired Mon Jun 14 18:12:44 2021 CEST
gpg: automatically retrieved '[email protected]' via WKD
pub   rsa4096 2016-06-15 [SC] [revoked: 2022-06-07]
      51585E1318770F501D3CBDE968FD03F8C6AB1DE4
uid           [ revoked] Old Nickname <[email protected]>
uid           [ revoked] Old User <[email protected]>
uid           [ revoked] Old Nickname2 <[email protected]>
sub   rsa4096 2016-06-15 [E] [revoked: 2022-06-07]

Even though [email protected] is the primary uid for the new key, gpg
shows the other uid for this key ([email protected]). This is odd, but
irrelevant. But then gpg proceeds to select the revoked key which is
somehow available via WKD.

The WKD test at https://metacode.biz/openpgp/web-key-directory delivers
similar results, but at least it displays the fingerprints of both the current
and the revoked key.

Two questions:

- Which WKD server hosts my expired/revoked key such that it takes precedence
  over my own WKD server at domain.com?
- Why does gpg select an expired/revoked key over a valid key?

Thanks,
Jan
