ERROR key generation error: no valid primary key self-signature or key(s) have expired

trying to add my public key into Keybase.

i run `keybase pgp select` from the commandline...

```
You are selecting a PGP key from your local GnuPG keychain, and
will publish a statement signed with this key to make it part of
your Keybase.io identity.

Note that GnuPG will prompt you to perform this signature.

You can also import the secret key to *local*, *encrypted* Keybase
keyring, enabling decryption and signing with the Keybase client.
To do that, use "--import" flag.

- ERROR key generation error: no valid primary key self-signature or key(s) have expired (Signature failure in packet 1: rejecting insecure hash SHA1 (35a84edd7d541840)) (error 905)
```

Start by reproducing `keybase pgp select` with the listed key and inspect the signature error, especially the rejected SHA1 hash and expired or invalid primary-key self-signature. No source files or tests are named in the issue; the issue is resolved when the key can be selected and published without the reported error.
