https://docs.openstack.org/sahara/pike/contributor/devstack.html

and this is devstack that I downloaded

git clone https://git.openstack.org/openstack-dev/devstack.git

and here is my local.conf

[[local|localrc]]

But the main problem is after I run stack.sh after it goes along and downloads some of the git files like sahara & heat it will come to this error, to be specific about it here is the error

I check every where that I should check and understood to check. But I think the main problem is related to pbr and the version of it with nutron or something else.

I'm totally new at this so sorry for not asking this in a better way

I'm installing devstack on a ubuntu server 20.04 vm
