Unable to add a PGP key with bash+GPG+cURL

When logged in to keybase.io, I receive an error from the following steps:

1. Click the "add a PGP key" link on my profile page.
2. Click "I have one already".
3. Paste my public key into the textarea and click "Upload".
4. Click "Maybe another time".
5. Choose "command line with [bash + GPG + cURL] " and click "Continue.
6. Run the given command in a terminal.

The command produces the following output:

Error in your post
-------------------

Code: 1007
Name: SIG_ELDEST_WITH_LIVE
Description: DB error

I'm running Debian testing with curl 8.13.0 and gpg 2.4.7. Any assistance would be appreciated.

Thanks,
Kevin

Start by reproducing the generated bash + GPG + cURL command from the profile flow and capture the response containing code 1007 and SIG_ELDEST_WITH_LIVE. Trace the PGP key upload request and its database error handling. Done means the documented command accepts the uploaded public key without the DB error.
