at work I have pbr (0.11.0) installed and stack deploys just fine so I'm not convinced pbr downgrading alone is what triggered the error. But I agree my home machine I'm using pbr 0.11.0 but also getting the same error after cloning keystone. Something is mangling test-requirments.txt after cloning which injects ";python_version='2.7'.
I can confirm there is a bug that is preventing devstack from deploying but can't confirm pbr is the cause.
