Open Stack

Guys,

I'm following the document:

http://docs.openstack.org/juno/install-guide/install/apt/content/trove-install.html

But it triggers an error:

---
root at controller-1:~# apt-get install python-trove python-troveclient
python-glanceclient trove-common trove-api trove-taskmanager

Reading package lists... Done
Building dependency tree
Reading state information... Done
python-glanceclient is already the newest version.
python-glanceclient set to manually installed.
python-troveclient is already the newest version.
python-troveclient set to manually installed.
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
* python-trove : Depends: python-sqlalchemy (< 0.9) but 0.9.7-1~cloud0 is
to be installed*
E: Unable to correct problems, you have held broken packages.

Is it expected to be fixed?

Thanks!
Thiago
