Dépendances non satisfaites après l'installation de CUDA 10.2

J'ai essayé d'installer cuda 10.2 en utilisant apt. A mi-parcours de l'installation, une erreur s'est produite. J'ai pu installer directement en exécutant le fichier .run à partir du site Web Nvidea. Mais maintenant, en faisant:

$ Sudo apt upgrade

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies.
 cuda-libraries-dev-10-2 : Depends: libcublas-dev (>= 10.2.2.89) but it is not installed
 cuda-samples-10-2 : Depends: libcublas-dev (>= 10.2.2.89) but it is not installed
 cuda-visual-tools-10-2 : Depends: libcublas-dev (>= 10.2.2.89) but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Puis en faisant:

$ Sudo apt --fix-broken install

Je reçois:

Use 'Sudo apt autoremove' to remove them.

Des idées sur la façon de réparer les paquets cassés?

Ok, j'ai pu trouver une solution en ligne:

1) J'ai changé les profils principaux en intel. 2) déplacé le fichier cuda.list ailleurs (la version 10.2 que j'avais installée) 3) Lignes commentées dans .bashrc où il indiquait le chemin vers cuda 10.2 (pas sûr si nécessaire) 4) redémarré 5) $ Sudo apt --fix- installation cassée

(et cela a fonctionné cette fois!)

6) profil principal commuté de nouveau à nvidia 7) lignes non commentées dans .bashrc (étape inverse 3) 8) $ source .bashrc

Et ça a marché. J'ai maintenant installé cuda 10.2 et apt n'a plus de dépendances cassées. :-)
