Unable to install owncloud-client in wheezy

[Peter Ley <peteley11235@gmail.com>]

Hi all,

I'm trying to install owncloud-client-cmd in wheezy and I get the
following:
--
Reading package lists... Done
Building dependency tree       
Reading state information... Done
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:
 owncloud-client-cmd : Depends: libowncloudsync0 (= 1.5.0+dfsg-4~bpo70+1) but it is not going to be installed
                       Depends: libocsync0 (>= 0.91.0) but it is not installable
E: Unable to correct problems, you have held broken packages.

And I also have this in sources.list.d/owncloud.list, per owncloud.org:
deb http://download.opensuse.org/repositories/isv:ownCloud:community/Debian_7.0/ /

Things I've done:
- apt-get update && apt-get upgrade
- apt-get clean
- apt-get -f
- dpkg --configure -a

I'm not really versed in the finer points of debian, so forgive me if
I've missed something obvious or done some unnecessary things. I've been
poking about on forum posts for a little while.
