Hey there Eva! And thank you for your reply.

I should perhaps clarify that signing anything else (documents, git commits) seems to work just fine. I can sign things, and then verify the signature, and it matches. My issue seems to solely relate to signing an extra uid. > Importing your second pubkey did not change anything noticeable, gpg reported > no changes on the key and there is no new UID to be seen. That is not the behaviour I am seeing on my end: $ gpg --import before.asc gpg: key 29AD46D6F58287A3: public key "Rens Rikkerink <cont...@ikkerens.com>" imported gpg: Total number processed: 1 gpg: imported: 1 gpg: no ultimately trusted keys found $ gpg --import after.asc gpg: key 29AD46D6F58287A3: 1 bad signature gpg: key 29AD46D6F58287A3: "Rens Rikkerink <cont...@ikkerens.com>" not changed gpg: Total number processed: 1 gpg: unchanged: 1 As you can see here, the second public key does trigger a slightly different response for me (1 bad signature), so it ignores it and marks the public key as otherwise unchanged. > To avoid any confusion does > > gpg -k 408FB2EBC3DF3DBBE0143D9A29AD46D6F58287A3 > > show the new UID for you? Yes, it does: $ gpg -k 408FB2EBC3DF3DBBE0143D9A29AD46D6F58287A3 gpg: checking the trustdb gpg: no ultimately trusted keys found pub ed25519 2022-10-26 [CA] 408FB2EBC3DF3DBBE0143D9A29AD46D6F58287A3 uid [ unknown] Rens Rikkerink <cont...@ikkerens.com> uid [ unknown] Rens Rikkerink <rens.rikker...@luminis.eu> sub ed25519 2022-10-26 [S] sub cv25519 2022-10-26 [E] > Is there additional info if you add "--list-options show-unusable-uids" > before the "-k"? No further information as far as I can tell: $ gpg --list-options show-unusable-uids -k 408FB2EBC3DF3DBBE0143D9A29AD46D6F58287A3 pub ed25519 2022-10-26 [CA] 408FB2EBC3DF3DBBE0143D9A29AD46D6F58287A3 uid [ unknown] Rens Rikkerink <cont...@ikkerens.com> uid [ unknown] Rens Rikkerink <rens.rikker...@luminis.eu> sub ed25519 2022-10-26 [S] sub cv25519 2022-10-26 [E] Thank you for your time so far.
