Building devstack in a CI/CD pipeline on CircleCI, Build failed: Unknown task: install_prereqs

I installed devstack on my mac an it worked fine, now I wanted to build a CI/CD pipeline for it on CircleCI but I am getting the error on this line

+ docker-compose exec -T lms bash -e -c 'source /edx/app/edxapp/edxapp_env && cd /edx/app/edxapp/edx-platform && NO_PYTHON_UNINSTALL=1 paver install_prereqs'
Build failed: Unknown task: install_prereqs

I am using ubuntu:20.04 image and have followed the steps for linux installation. These are the commands I’m running but it throws an error on the provisions command

cd devstack
git checkout open-release/nutmeg.master
make dev.checkout
make requirements
make dev.clone
make dev.pull.large-and-slow
make dev.provision
make dev.up.large-and-slow
make studio-shell
pytest cms

How could I solve this issue?

I don’t know the answer to your question, but is there a reason you’re not using the latest release (Palm) and Tutor instead of devstack?
