I just ran into this issue because I was installing a package that was bringing in keystonemiddleware 1.5.x which was downgrading pbr to <1.0. I fixed this problem by upgrading keystonemiddleware to 2.x.x with:
pip install -U keystonemiddleware After that, devstack worked fine again. This break happened after the RDO packages used in devstack were changed from Juno to Kilo.
