ERROR EOF on `keybase pgp gen`

I'm getting `ERROR EOF` when running `keybase pgp gen` in ubuntu 16.04

```
charles@leopard:~$ keybase pgp gen
▶ INFO Forking background server with pid=5693
Enter your real name, which will be publicly visible in your new key: Charles Verdad
Enter a public email address for your key: ****@gmail.com

Enter another email address (or when done):
Push an encrypted copy of your new secret key to the Keybase.io server? [Y/n] Y

▶ ERROR EOF
```
I tried this in the default gpg installed in 16.04 as well as gpg2.1 by running `keybase config set gpg gpg2` I also uninstalled all gpg and installed gpg2.2 using the guide in https://gist.github.com/vt0r/a2f8c0bcb1400131ff51

```
charles@leopard:~$ gpg --version

Reproduce `keybase pgp gen` on Ubuntu 16.04 with the reported GnuPG versions and the listed interactive answers. Trace the EOF around the encrypted key push and GnuPG keychain export, then verify that key generation completes without the error and produces the requested key.
