Hi, you need to set the CI/CD config file to "debian/salsa-ci.yml" for your project, under Settings / CI/CD/ General pipelines.
It should be set correctly by our "setup-project"/"setup-project-mentors" script in the meta repository, as the ci_config_path is set by the create_project function (see lib/salsa.rb). I looked for example at: https://salsa.debian.org/ruby-team/mentors/ruby-fixture-builder for which the setting was at the default value (.gitlab-ci.yml). I manually put it to debian/salsa-ci.yml, and pushed a trivial commit to it. The pipeline started as expected. I hope it helps. Best wishes, Cédric
