while testing GpgOL I answered the following with "yes":
The "Confirm your key publication" E-Mail received after that (the subject was in english despite german language settings, body was in german) triggert a GpGOL question "Confirm entry", the confirmation then resulted in the following error message:
You get this error because the key has been created in gnupg mode (and not in de-vs) and thus it has these preferences.
Cipher: AES256, AES192, AES, 3DES AEAD: OCB, EAX Digest: SHA512, SHA384, SHA256, SHA224, SHA1 Compression: ZLIB, BZIP2, ZIP, Uncompressed Features: MDC, AEAD, Keyserver no-modify
The web key service also runs with GnuPG 2.3 and thus uses OCB mode as requested by the preferences. Now the client system running in de-vs mode rightfully rejects this. The error message could be better but given that we will move to OCB in the long term anyway, I don't see a reason for special handling of this case.
This web service is not localized. I have this in my agenda but it is not really relevant. IIRC, KMail has dedicated handling for this and does its own localization instead of using the standard messages from the mail.
