Heroku push hanging on “fetching gem metadata from

Question

My deployment is stuck on fetching gem metadata from rubygems every time I deploy.
It worked this morning, had problems this afternoon and now it's not working again.
We tried from somewhere else and from other computers with the same result.

It works fine locally I can update from rubygems without a problem.

Visual:

Delta compression using up to 4 threads.

Writing objects: 100% (9/9), 764 bytes, done.

[IT HANGS HERE FOREVER]

Anyone has a clue?

Answer 1

Fixed by adding bundler to the gem file and forcing a version

gem 'bundler', '1.2.1'

Answer 2

Ok, fixed for good I think. Turns out it only works when explicitly specifying the last versions of heroku and bundler. The strange thing is that it can bundle without the explicit versions locally but not when deploying to heroku.

gem 'heroku', '2.33.0'
gem 'bundler', '1.2.1'

Answer 3

For me changing the protocol to fetch gem fixed the problem.

I changed https://github.com/epetre/negative-captcha.git to git://github.com/epetre/negative-captcha.git in gem file. Bundled it and pushed to heroku and it works.
