This is my first deploy - all steps I've made according to GoRails Tutorial: https://gorails.com/deploy/ubuntu/16.04

After "cap production deploy" command I receive that error message:

MacBook-Pro:app admin$ cap production deploy --trace
** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
cap aborted!
Don't know how to build task 'deploy:setup' (see --tasks)

What's wrong?

Results for "cap production deploy --trace":

MacBook-Pro:app admin$ cap production deploy --trace
** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
cap aborted!

That tutorial is horribly out of date. Here's what I would change (starting at the Capistrano Setup heading):

For both the rbenv and rvm gemfile entries, drop the github: 'something' part. The released Gem versions have been stable for a long time.

In the Capfile, they are correct that the require lines go in there, but the set lines should go in config/deploy.rb.

In config/deploy.rb, the restart section can be entirely replaced with the capistrano-passenger gem. That Gem's readme has instructions for installation. In general, it'll use passenger commands to perform the application restart, but you can also tell it to use the touch method which is identical to what the restart section is doing. You can also remove the after :finishing, 'deploy:cleanup' line.

In config/deploy/production.rb, you can remove set :stage, 'production'. You only need to set the stage if it is different from the filename.

Also, make sure you are running the latest versions of all the relevant gems by running bundle update gemname.
