# and the Ceph packages in the Pike UCA are pulling in python-paste and
# python-pastedeploy packages. The python-pastedeploy package satisfies the
# upper-constraints but python-paste does not, so devstack pip installs a
# newer version of it, while python-pastedeploy remains. The mismatch
# between the install path of paste and paste.deploy causes Keystone to
# fail to start, with "ImportError: cannot import name deploy."
