Bug#875626: marble: Unsatisfied build-deps

[Thomas Braun <thomas.braun@virtuell-zuhause.de>]

Package: marble
Version: 4:16.08.3-1
Severity: normal

Dear Maintainer,

executing `apt-get build-dep` gives

Reading package lists... Done
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:
 builddeps:marble : Depends: libopencv-highgui-dev but it is not going
 to be installed
 E: Unable to correct problems, you have held broken packages.

I would have expected that this command works.

Thanks,
Thomas
