gpgv 2.2.12-1ubuntu3 (s390x binary) in ubuntu eoan

 GnuPG is GNU's tool for secure communication and data storage.
 .
 gpgv is actually a stripped-down version of gpg which is only able
 to check signatures. It is somewhat smaller than the fully-blown gpg
 and uses a different (and simpler) way to check that the public keys
 used to make the signature are valid. There are no configuration
 files and only a few options are implemented.
