Interesting. I haven't seen this error before:

  # gpg: Signature made Tue 23 Apr 2019 12:54:49 PM PDT
  # gpg:                using RSA key 60AB47FFC9095227
  # gpg: bad data signature from key 60AB47FFC9095227: Wrong key usage
(0x00, 0x4)
  # gpg: Can't check signature: Wrong key usage

I think it means that you signed it with a key that was marked for
encryption only or something like that.

But gpg being the wonderful self-explanatory great UX that it is, I
have no effin clue what it really means.

Looking at the git history, it turns out this has happened a before
from you, and in fact goes back to pull requests from 2012.

Either I just didn't notice - which sounds unlikely for something that
has been going on for 7+ years - or the actual check and error is new
to gpg, and I only notice it this merge window because I've upgraded
to F30.
