--search-keys: "gpg: error searching keyserver: No inquire callback in IPC"

[Rainer Fiebig]

Hi! I'm having a problem when searching for keys on keyservers when
using "gpg --search-keys".

The only line in dirmngr.conf (except for comments) is:
keyserver hkps://keys.openpgp.org

gnupg version is 2.2.29 but I also see this with 2.2.27.

Locale is German but "Kein "Inquire" "Callback" für IPC gesetzt" should
be equivalent to "No inquire callback in IPC". Sorry.

However, this (and only this) works:

~> gpg --keyserver keyserver.ubuntu.com --search-keys

Any ideas? Thanks.
