'git clone' asks for auth and then fails

[jordansissel]

I have two confusions. First, that 'git clone' (hub clone) is asking me for credentials for a public repo. Ignoring that, even after providing credentials, it fails. I've doublechecked the two-factor code sent to my phone and it was correct.

hub version 1.11.2

% git clone elasticsearch/elasticsearch
github.com username: jordansissel
github.com password for jordansissel (never stored):
two-factor authentication code: 462411
/Users/jls/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/net/http/response.rb:119:in `error!': 422 "Unprocessable Entity" (Net::HTTPServerException)
        from /Users/jls/.rvm/gems/ruby-2.0.0-p353/gems/hub-1.11.2/lib/hub/github_api.rb:333:in `obtain_oauth_token'
        from /Users/jls/.rvm/gems/ruby-2.0.0-p353/gems/hub-1.11.2/lib/hub/github_api.rb:319:in `obtain_oauth$token'

You should first upgrade to the latest version (1.12.0).

Now, the credentials aren't for cloning the repo itself (the repo is public, after all). Hub asks you for your credentials in general so it can cache the OAuth token for all future communication with the GitHub API on your behalf. This is a one-time operation.

The 422 is weird and may indicate a bug with the GitHub API. Please upgrade hub to the newest version, try again, and paste me the error message if it happpens to contain more information than before.

If the error is identical, you can use HUB_VERBOSE=1 git clone ... to obtain a dump of HTTP traffic that you can paste me (with parts anonymized, if needed).

Confirmed upgrading fixed it. Thanks for the quick response. :)

I'm getting a similar-looking problem, but with hub v1.12.0 already installed.

$ git --version                                                                               [19:28:53]
git version 1.8.5.2 (Apple Git-48)
hub version 1.12.0

When I HUB_VERBOSE=1 git clone 2-n, here's the important-looking part before the failure:

@alxndr This sounds like #531 and #563. Please follow the latter for updates

I fixed the issue by deleting a token named "hub" from the Personal access tokens area of https://github.com/settings/applications. I don't remember how it got there, but hub ci-status ended up complaining like this:

Error fetching CI status: Unprocessable Entity (HTTP 422)
Duplicate value for "description"

@alxndr This got fixed in v1.12.1
