Problem pushing secret key and proving identities

Hi, I'm facing an issue where I can't upload my secret key ($ and website tested), and also I can't prove identities. I've tried with subkeys and with masterkey, but nothing. `keybase push -s` returns `error: string is not a function` and `keybase prove twitter` returns `error: serginator: signature verification failed`.

I've configured it before without subkeys and it worked, but now I have a new key, I removed the keys from keybase and launch `keybase reset` to reconfigure it again, and now I don't know how to proceed.

Edit: After more tests it more or less works, I can't upload my master key but looks like I can use the cmd and prove my identities so... works for me, sorry for opening an issue

Start by reproducing `keybase push -s` and `keybase prove twitter` after the `keybase reset` flow, testing both the master key and subkeys described in the report. Done means the failure is consistently reproduced and its scope is identified, or both key upload and identity proving work reliably.
