Ottengo il seguente errore:

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.
Le politiche sembrano essere corrette:
$ apt-cache policy linux-image-amd64

Quindi non capisco l'errore. Che cosa sto facendo di sbagliato?
Sto cercando di usare Puppet per aggiornare tutte le macchine Wheezy al kernel backport (è prevista una sequenza di riavvio), motivo per cui voglio risolverlo correttamente. Potrei accedere manualmente a tutti i server per eseguire:
sudo apt-get install -t wheezy-backports linux-image-amd64
Che funziona, ma non è così conveniente.
AGGIORNARE
Come richiesto:
