brute-force clean of gpg data

    killall gpg-agent
    cd /root/.gnupg
    rm -rf \
     secring.gpg \
     private-keys-v1.d/ \
     agent.info \
     .gpg-v21-migrated \
     pubring.gpg \
     trustdb.gpg \
     crls.d/

re-init

    gpg --list-keys
        gpg: keybox '/root/.gnupg/pubring.kbx' created
        gpg: /root/.gnupg/trustdb.gpg: trustdb created

check after re-init

    ls -al
        total 40K

        -rw-------    1 root root   40 Nov 21 13:13 trustdb.gpg

NOTE the change: pubring.gpg -> pubring.kbx

force a refresh, supposedly with auto-import ON,

    zypper -vvv --gpg-auto-import-keys --no-gpg-checks ref --force

all keys are re-retrieved ... no interaction, or errors

recheck

    ls -al /root/.gnupg
        total 40K
        drwx------    4 root root 4.0K Nov 21 13:13 ./

        -rw-------    1 root root   40 Nov 21 13:13 trustdb.gpg

there's NO changes in any gpg data.  that seems wrong.

fwiw,

> prove to myself that the auto-import is/isn't failing

I haven't managed that, but I am a bit confused by the above.

Is there a specific test that'd answer the question -- does zypper's key
auto-import work correctly?
