Redmine installing problems Ubuntu 12.04

Question

I'm trying to install Redmine based on Official Wiki, but when I try to run rake generate_secret_token the following error shows

rake aborted!
Don't know how to build task 'generate_secret_token'

I already went into this question with no success

Redmine: rake error when installing

** For the problem above, I believe running the command rake secret has resolved, cause no generate_secret_token is listed when I call rake -T **

And when I try to run RAILS_ENV=production rake redmine:load_default_data I get

rake aborted!
Don't know how to build task 'redmine:load_default_data'

Following is the trace:

At end I solved my problem installing Bitnami's package for Redmine http://bitnami.com/stack/redmine

The generate_secret_token task is only available for Redmine >= 2.0.0. If you use an older version (which seems likely), the related task is called generate_session_store As such, try

bundle exec rake generate_session_store
