It seems it's a common problem that after updating Gitlab-omnibus something doesn't work anymore.
This time, updating from (ca.) 8.10 to 8.12.3 causes "500" errors to appear on any page request, so I can't use Gitlab at all. gitlab-rake gitlab:env:info System information System: Ubuntu 14.04 Current User: git Using RVM: no Ruby Version: 2.3.1p112 Gem Version: 2.6.6 Bundler Version:1.13.1 Rake Version: 10.5.0 Sidekiq Version:4.1.4 GitLab information Version: 8.12.3 Revision: 467e1ca Directory: /opt/gitlab/embedded/service/gitlab-rails DB Adapter: postgresql URL: https://git.openlilylib.org HTTP Clone URL: https://git.openlilylib.org/some-group/some-project.git SSH Clone URL: g...@git.openlilylib.org:some-group/some-project.git Using LDAP: no Using Omniauth: yes Omniauth Providers: github GitLab Shell Version: 3.6.1 Repository storage paths: - default: /var/opt/gitlab/git-data/repositories Hooks: /opt/gitlab/embedded/service/gitlab-shell/hooks/ Git: /opt/gitlab/embedded/bin/git ########## and # tail -n 25 gitlab-rails/production.log ActiveModel::MissingAttributeError (missing attribute: issues_enabled): app/models/ability.rb:315:in `project_disabled_features_rules' app/models/ability.rb:98:in `anonymous_project_abilities' app/models/ability.rb:59:in `anonymous_abilities' app/models/ability.rb:5:in `allowed' app/controllers/application_controller.rb:126:in `can?' app/controllers/projects/application_controller.rb:29:in `project' lib/gitlab/middleware/go.rb:16:in `call' Started GET "/bfsc/das-trunkne-lied/blob/508f7aa37b34d5cd9a95eb852db95dd617b1d24e/printed-parts/BassoonII.ly" for 164.132.161.34 at 2016-10-02 15:35:53 +0200 Processing by Projects::BlobController#show as */* Parameters: {"namespace_id"=>"bfsc", "project_id"=>"das-trunkne-lied", "id"=>"508f7aa37b34d5cd9a95eb852db95dd617b1d24e/printed-parts/BassoonII.ly"} Completed 500 Internal Server Error in 42ms (ActiveRecord: 3.8ms) ActiveModel::MissingAttributeError (missing attribute: issues_enabled): app/models/ability.rb:315:in `project_disabled_features_rules' app/models/ability.rb:98:in `anonymous_project_abilities' app/models/ability.rb:59:in `anonymous_abilities' app/models/ability.rb:5:in `allowed' app/controllers/application_controller.rb:126:in `can?' app/controllers/projects/application_controller.rb:29:in `project' lib/gitlab/middleware/go.rb:16:in `call' Any suggestion to further pin down or even fix the issue?
