The issue seems to be that during a capistrano deploy the created cron job has RAILS_ENV=staging as expected since the deployment environment is staging. However, in a capistrano rollback the created cron job has RAILS_ENV=new_staging where new_staging is the capistrano stage being rolled back.

Whenever Version (0.9.7)
Capistrano Version (2.12.0)
What is causing the rollback to use the capistrano stage instead of the rails_env when running Whenever gem? And how can I get it to properly use the rails_env?
I'm a little confused by your staging setup (what is the difference between staging and new_staging?). That said, you should be able to do this by changing your whenever_environment to use rails_env instead of the stage value set by capistrano:
so
set :whenever_environment, defer { stage }
Would become:
set :whenever_environment, defer { rails_env }

I need some help. Its a multi rails app server. Please ask any more info if you need. I have also replaced site and github url with .... because of site security.
There is no thin process running on your server, that's why you're getting the Can't stop process, no PID found error. I suggest starting thin manually so your deploy script can then successfully restart it.

I don't know what to do !
Can somebody help me ?
Thanks a lot !
That is a very old version of Capistrano (2.0.0 is from July 2007, and doesn't support changes in Ruby 1.9/2.0 -- in this case, Ruby 1.9 no longer allowed using instance variables as arguments to blocks).
You'll need to upgrade to the newest 2.x release (2.15.5).
You could also upgrade to Capistrano v3, but keep in mind it was a complete rewrite and your existing configuration will not be compatible with v3 without some work.
I worked on being able to deploy to production using capistrano. I face several issues and while fixing most of them we still have a last one.
Our precompile assets options are not properly compiling them on production and because of that, we are unable to use the last developed features as they rely heavily on JS.
Without trying to influence on how anyone would analyze this problem, this is some of what I did trying to make it work:
Precompiled assets locally, pushed to github repo, cap deployed from local machines to ec2. cap deploy is local, the code being pushed to ec2 is the one on github.
Tried using capistrano tasks as suggested. Using load 'deploy'assets' in the Capfile and letting the cap deploy:setup task do its thing.
Used the option cap deploy:assets:clean and then cap deploy:assets:precompile
Tried removing assets from public and then use a pipeline_precompile task in deploy.rb
Expired assets, forcing rails to precompile everything changing assets.versions in application.rb
Tried different combinations on config.assets in environments/production.rb
Finally, tried deleting public/assets in production and precompiling up there using RAILS_ENV=production bundle exec rake assets:precompile
The app is just not using the new JS files. If you check the code either on the repo or in the server itself, I introduced a simple comment to the name.js.coffee ("# Shows and hides menus depending on the data on DB" on line xxx) and this is not in the compiled assets.js in production. This is a quick test to be sure the recent assets are being used.
The whole problem here is the js and css files, not so much rails. Which is why it is so difficult to test or find.. Thus one of the reasons for the popularity of js frameworks lately. In case of problems, you don't have to kill yourself looking for where the problem is.. If the prob is in ruby or rails, usually doesn't take that long to find out. Once you get to js, css and cross browser compatibility, well, this IS the problem at hand.

Thank you in advance for any help! Let me know if you need more info.
You don't need your own :precompile_assets task. You are using Capistrano's by including load 'deploy/assets' in your Capfile.
Removing the :precompile_assets task from your deploy.rb may resolve the issue. If you look at the source code for Capistrano, you'll see it implements :precompile_assets quite differently: https://github.com/capistrano/capistrano/blob/legacy-v2/lib/capistrano/recipes/deploy/assets.rb

I found that the capistrano asset compile rules got run before the bundler rules, so nothing worked, I wrote my own:
after "bundle:install" do
run "cd #{release_path}; RAILS_ENV=production bundle exec rake assets:precompile"
end
I then found that I really wasn't interested in installing a js runtime on my production machines. I went back to just putting my assets into a deploy branch of my git tree.
First time I did this, I forgot to include the manifest.yml file.

If you have uglifier in Gemfile, which runs during asset compilation, it may have been configured to remove just the sort of comment you are using as a test for whether the changed Javascript assets are being deployed.
Uglifier's Readme says this is possible, and distinguishes several kinds of comments. So it's possible you may have been misled by seeing another comment still remaining after asset compilation.
Another clue to judging this possibility is that (as you say) this problem arose after a long (tiring) process of fixing other problems. Often, this can block people from a perception like this; a long effort can 'lock them in' to an assumption.
So, try adding a variable declaration instead of a comment, in your Javascript.
I had an issue similar to this but the solution was to remove the assets group in the Gemfile, as the default task cap uses to precompile depends on the assets not being in a separate group seemingly.
I encountered this problem. Turns out I had to install node and yarn on my servers for rake assets:precompile to work
I also had this issue recently, asset precompilation with Capistrano deployment was hanging in AWS. I solved the issue by switching from a t3.micro instance to a t3.small instance temporarily while I deployed. It looks like the micro instance did not have enough resources for the precompilation step.
I am deploying to Ubuntu with Capistrano.
I have God + Resque set up for background process.
App runs fine and Resque workers are going to their queues, but are stuck there. When I looked into logs, I found out that it's Rake failing. Here is the trace:

Last note - everything works fine if I don't use Capistrano (e.g. just copy Rails app folder to server).. so I guess I am missing something on Capistrano side..
So it turns out that my redis folder had permissions problem and could not write to the database. So I checked where the database file is being saved (or rather not saved in my case) and did sudo chown redis:redis now all is good.
