Hi, I have tried to replicate your issue using a Yubikey 5 NFC, doing what you did. > In general, I don't think my procedure for adding a new uid is abnormal: > $ gpg --edit-key 408FB2EBC3DF3DBBE0143D9A29AD46D6F58287A3 > gpg> adduid > gpg> save
For my key and using gpg 2.4.5 on a standard Windows 10 system "check" didn't give an error and signing a document worked without any issues. I used a simple brainpool standard testkey with only one subkey, though. > General info: > OS: Windows 11 (AtlasOS) & MacOS 14.1.1 (tried on both) > GPG: GPG 2.4.4.-unknown (bundled with git-scm windows installer), GPG > 2.4.5 (homebrew) > > My public keys: > Before trying to add a new uid: > After trying to add a new 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. So it seems it was not exported. To avoid any confusion does gpg -k 408FB2EBC3DF3DBBE0143D9A29AD46D6F58287A3 show the new UID for you? Is there additional info if you add "--list-options show-unusable-uids" before the "-k"? Regards Eva -- g10 Code GmbH GnuPG.com AmtsGer.
