sidekiq cannot be started

Created by: perryfaro

I just did a update from gitlab 6-1 to 6-2. everything went well until I want to start sidekiq.

I use this command to start:

bundle exec rake sidekiq:start RAILS_ENV=production

And I get this error:

rake aborted!
Don't know how to build task 'sidekiq:start'

Also when I run the check I get now an error on gitlab-shell :

gitlab-shell self-check failed
  Try fixing it:
  Make sure GitLab is running;
  Check the gitlab-shell configuration file:
  sudo -u git -H editor /home/git/gitlab-shell/config.yml
  Please fix the error above and rerun the checks.
