我是 openstack 新手，我正在尝试设置我正在使用 Ubuntu 14.04 映像的一体化环境
我正在关注本指南： http: //fosskb.in/2015/10/20/openstack-liberty-on-ubuntu-14-04-and-ubuntu-15-10/
使用以下命令安装 keystone 时：
apt-get install -y keystone apache2 libapache2-mod-wsgi memcached python-memcache python-openstackclient
它告诉我以下软件包具有未满足的依赖关系：
keystone : Depends: python-keystone (= 2:8.0.1-0ubuntu1~cloud0) but 1:2014.1.5-0ubuntu1 is to be installed
python-openstackclient: Depends: python-cinderclient (>= 1:1.3.1) but 1:1.0.8-0ubuntu2 is to be installed
Depends: python-glanceclient (>= 1:0.18.0) but 1:0.12.0-0ubuntu1 is to be installed
Depends: python-keystoneclient(>= 1:1.6.0) but 1:0.7.1-ubuntu1.3 is to be installed
Depends: python-neutronclient(>= 1:2.6.0) but it is not going to be installed
Depends: python-novaclient(>= 2:2.28.1) but 1:2.17.0-0ubuntu1.2 is to be installed
Depends: python-oslo-serialization (>= 1.2.0) but it is not going to be installed
Depends: python-oslo.utils (>= 2.0.0) but it is not going to be installed
aptitude 告诉我 python-keystone 有以下依赖不可用或不满足：
python-cryptography (>= 1.0) (unavailable)
python-keystoneclient (>= 1:1.6.0) (unsatisfied)
python-keystonemiddleware (>= 2.0.0) (unsatisfied)

如何解决这些依赖关系？
