Erro for installation of CUDA, Ubuntu 16.04

Since yesterday, I am trying to install the Cuda toolkit 9.2 on two different computers working with ubuntu 16.04.
For both computers, I have the same error saying that the downloaded file is not a debian file:

sudo dpkg -i cuda-repo-ubuntu1604-9-2-local_9.2.148-1_amd64.deb
dpkg-deb : erreur : `cuda-repo-ubuntu1604-9-2-local_9.2.148-1_amd64.deb » n’est pas une archive de format Debian
dpkg: erreur de traitement de l’archive cuda-repo-ubuntu1604-9-2-local_9.2.148-1_amd64.deb (–install) :
le sous-processus dpkg-deb --control a retourné une erreur de sortie d’état 2
Des erreurs ont été rencontrées pendant l’exécution :

I wanted to chek the sums, but the sums for this library is not given in .

md5sum cuda-repo-ubuntu1604-9-2-local_9.2.148-1_amd64.deb

DO you think that the problem is coming from the nvidia file?
