Hi all.

I'm trying to upgrade my current local Canvas installation, but when I try to run:
RAILS_ENV=production bundle exec rake db:load_notifications

I'm getting this error message (trace enabled for debug):

# RAILS_ENV=production bundle exec rake db:load_notifications --trace
** Invoke db:load_notifications (first_time)
** Invoke db:load_environment (first_time)
** Invoke db:generate_security_key (first_time)
** Execute db:generate_security_key
rake aborted!

This sounds like an issue with your security.yml, not the Canvas code.

It is an upgrade, my security.yml was not changed.

I've already did many upgrades in this base without errors, but this time I had this in rake db:load_notifications migrate.

security.yml file content (encryption_key values replaced):

production: &default
  # replace this with a random string of at least 20 characters
  encryption_key: XXXXXXXXXXXXXXXXXXXXXX
  lti_iss: 'https://canvas.instructure.com'

development:
  <<: *default
  encryption_key: YYYYY
  previous_encryption_keys:
    - ZZZZZZ

test:
  <<: *default
  encryption_key: WWWWWWW

Remove &default from the production key and comment out the development and test blocks, like so:

production:

  # replace this with a random string of at least 20 characters
  encryption_key: XXXXXXXXXXXXXXXXXXXXXX
  lti_iss: 'https://canvas.instructure.com'

#development:
#  <<: *default
#  encryption_key: YYYYY
#  previous_encryption_keys:
#    - ZZZZZZ

#test:
#  <<: *default
#  encryption_key: WWWWWWW
