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:
linux-image-amd64 : Depends: linux-image-3.16.0-0.bpo.4-amd64 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
As políticas parecem estar corretas:
$ apt-cache policy linux-image-amd64

Então eu não entendi o erro. O que estou fazendo errado?
Estou tentando usar o fantoche para atualizar todas as máquinas Wheezy para o kernel de backports (uma sequência de reinicialização está planejada), e é por isso que quero resolvê-lo corretamente. Eu poderia acessar manualmente todos os servidores para executar:
sudo apt-get install -t wheezy-backports linux-image-amd64
O que funciona, mas não é tão conveniente.
ATUALIZAR
Como pedido:
/etc/apt/preferences.d$ cat linux-image
Package: linux-image-*
Pin: release a=wheezy-backports
Pin-Priority: 1001
Package: *
Pin: release a=wheezy-backports
Pin-Priority: 499
/etc/apt/preferences.d$ sudo apt-get update
Hit http://debian.kumina.nl wheezy-kumina Release.gpg
