no public key for 1397BC53640DB
I tried just clicking on it and using my password and it wouldn't let me access it. I decided I had my quota of aggravation for this issue so, I reinstalled Mint and upgraded to 17.3. I realize that is not always a viable solution, but for me it was, at that time. If anyone comes up with a another solution I would really like to hear about it. Please accept my gratitude for your time and patience.
