Think I found the answer, I was using the wrong command.  Should have been edit, not lsign-key.  Will test the following tomorrow.


gpg --edit-key 1234567890ABCDEF

type:   fpr
Displays the key’s fingerprint

Type:    trust.   

1 = I don't know or won't say
  2 = I do NOT trust
  3 = I trust marginally
  4 = I trust fully
  5 = I trust ultimately
  m = back to the main menu

Type   save    to exit after setting.
