Site has been migrated from Heroku to a dedicated Ubuntu server, and after the migration site is working normally, except for the images which are on hosted on S3.

When loading pages with images on it, following type of error would be returned:

Completed 200 OK in 1428.8ms (Views: 505.5ms | ActiveRecord: 322.2ms)

Dragonfly::Configurable::NotConfigured (You need to configure Dragonfly::DataStorage::S3DataStore with bucket_name):

I can see that application didn't have dragonfly listed in gemfile,as Heroku seems to do things a little differently, and have reinstalled dragonfly, but when trying to generate a configuration file following error is returned.

Recaptcha itself seems to be working fine, and bundle install didn't return any errors, but I can't get dragonfly to work.

recaptcha.rb looks like this

Recaptcha.configure do |config|
  config.public_key  = 'public key'
  config.private_key = 'private key'
  config.api_version = 'v2'
end

I have created .env file which didn't exist, with following content:

export RECAPTCHA_PUBLIC_KEY = 'public key'
export RECAPTCHA_PRIVATE_KEY = 'private key'

I also tried manually adding to config/environments/production.rb, and config/environments/development.rb following:

recaptcha_public_key= "[PUBLIC KEY]"
recaptcha_private_key= "[PRIVATE KEY]"

I am not sure what I a missing here, does anybody have any experience with dragonfly and recaptcha after migrating from Heroku to standalone Linux system

They changed the API with version 4, so if you're installing it through the gemfile without specifying version and it defaults to version 4, you'll need to make changes in your config.

From their CHANGELOG.md:

4.0.0 - 2016-11-14

public_key -> site_key and private_key -> secret_key

Change your config/initializers/recaptcha.rb to this:

Recaptcha.configure do |config|
  config.site_key  = 'public key'
  config.secret_key = 'private key'
  ...

Also try removing config.api_version = 'v2' – Lug
