Hi guys! Heads up: If you have ever generated or imported a gpg secret key using gpg 1 or 2.0 (ie, before Stretch), then used --delete-secret-key, please rm ~/.gnupg/secring.gpg (and shred/trim/balance/etc -- it's a huge topic).
If you --delete-secret-key with gpg 2.1, it deletes the key only from its own copy but leaves the gpg 1/2.0 copy intact. Querying it with --list-secret-keys doesn't reveal that the key is still there, either. But, if you rm .gpg-v21-migrated, that "deleted" key is back. Yay if you cross a border, have your disk seized or imaged, or share the machine. Double yay if you had it imaged in the past.
