Bug#855024: Install nvidia-driver package from jessie-backports using different methods

[Markus Lindberg]

Package: nvidia-driver
Version: 375.26-1~bpo8+1

I have tried two different methods to install the 'nvidia-driver' 
package from the 'jessie-backports' repository using 'apt-get' and only 
one method succeeds. As far as I know you can install a package from 
'jessie-backports' by using two different methods. Method one would be 
to use the option 'apt-get install -t jessie-backports nvidia-driver' 
and the second one would be 'apt-get install 
nvidia-driver/jessie-backports'. But the second method fails for the 
'nvidia-driver' package.

Here is a sample output from both commands:

# apt-get install -t jessie-backports nvidia-driver

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:
  nvidia-driver : Depends: nvidia-driver-libs (= 375.26-1~bpo8+1) but it 
is not going to be installed
                  Depends: nvidia-driver-bin (= 375.26-1~bpo8+1) but it 
is not going to be installed

going to be installed
                  Recommends: nvidia-persistenced but it is not going to 
be installed
E: Unable to correct problems, you have held broken packages.

As you can see the second commands fails as a result of unsolved 
dependencies. The previous version of the 'nvidia-driver' package 
'367.57-2~bpo8+1' could be installed using both methods.
