gpg 2.4.3 complains about not being able to export my key. The issue is it can not query the secring password from my ssh session. How to debug this further? gpg: key 89DE8BFC8A2A81F8C9BD2F7940C7373A4DE34E7C: error receiving key from agent: Operation cancelled - skipped keyserver-options no-include-revoked import-clean-sigs import-clean-uids export-clean-sigs export-clean-uids default-preference-list SHA512 SHA384 SHA256 SHA224 AES256 AES192 AES CAST5 BZIP2 ZLIB ZIP Uncompressed 2023-09-04 19:24:14 gpg-agent[88711] failed to unprotect the secret key: Verarbeitung wurde abgebrochen 2023-09-04 19:24:14 gpg-agent[88711] command 'EXPORT_KEY' failed: Verarbeitung wurde abgebrochen <Pinentry> 2023-09-04 19:24:43 gpg-agent[88711] failed to unprotect the secret key: Verarbeitung wurde abgebrochen 2023-09-04 19:24:43 gpg-agent[88711] command 'EXPORT_KEY' failed: Verarbeitung wurde abgebrochen <Pinentry> lrwxr-xr-x 1 root wheel 12B 31 Aug. 08:20 /usr/local/bin/pinentry@ -> pinentry-tty -r-xr-xr-x 1 root wheel 71K 1 Sep. 00:13 /usr/local/bin/pinentry-curses* -r-xr-xr-x 1 root wheel 61K 31 Aug. 03:00 /usr/local/bin/pinentry-tty* If I specify --pinentry-mode loopback it works. Shouldn't this also work without this option? If yes, what's wrong or how to debug this further?
