Which of our tools is giving you problems? GPGmail for OSX

Attach a screenshot of the version info for all installed components (how to:

Describe your problem. Add as much detail as possible. I sent a signed email -- my default setting.
The response came back with no body, just a footer, and an error. Clicking details yielded the screenshot. The encryption icon showed for this message.

What did you expect instead An unencrypted reply.
Or one encrypted with my public key, transparently decrypted.

Describe steps leading to the problem.

Are you using any other plugins?

    I received strange errors in my clients after the upgrade because the secret keys had failed to be migrated during the upgrade.

    Can you see your secret keys in GPG Keychain?

    If you can't, It's been suggested that you can re-import them from ~/.gnupu/secring.gpg.

    Hi ctwardy,

    welcome to the GPGTools support platform. Sorry you are having problems using GPG Suite.

    With GPG Suite 2017.1 we have upgraded our version of GnuPG (MacGPG2) from GnuPG 2.0 to GnuPG 2.2.

    The error message you are reporting indicates that there kay have been a problem migrating your secret key.

    Please visit the following KB-article and let me know if that brings you back to working state.

    All the best,

    That looks relevant! I've run the command, saw some imports, and will presume it solved. Thank you!

    Have you tried sending yourself an encrypted and signed test message? Are you able to sign and decrypt as expected?
