ruby on rails - cap rubber:create_staging failed near end -

i trying deploy aws sample rubber test in quick start wiki https://github.com/rubber/rubber/wiki/quick-start

i past part prompts local machine password write hosts file ( creates roles, instance, , lot of other things; got through error not connecting - renamed private key without .pem extension , fixed ), , runs on while, , gives error here:

i got same failure, , looking above line @ output command, saw uwsgi-plugin-http package needs replaced uwsgi-core package.

there apparently a pull request fix this has not yet been accepted, can fix making same edit: on rubber 2.8.1, open config/rubber/rubber-graphite.yml, go line 22, , should this:

    packages: [python-django, python-django-tagging, python-cairo, python-memcache, memcached, uwsgi, uwsgi-plugin-python, uwsgi-plugin-http, sqlite3, bzr, zip] 

replace uwsgi-plugin-http uwsgi-core line be:

    packages: [python-django, python-django-tagging, python-cairo, python-memcache, memcached, uwsgi, uwsgi-plugin-python, uwsgi-core, sqlite3, bzr, zip] 

then, run cap rubber:bootstrap, , should finish setting instance.
