I guess some nasty mess is going on with drivers upgrade. After an upgrade in Ubuntu 18.04 I got nvidia drivers messed up and, as a consequence, my cudnn and tensorflow production machine reverted to nouveau drivers. Let us wait for some hours that repositories get updated.

My 18.04 had the same issue since last week after I did the update. If anyone out there know a solution, please help.

I had that problem, too, and it’s solve by force overwrite the package by following command

sudo dpkg -i --force-overwrite /var/cache/apt/archives/libnvidia-compute-450_450.36.06-0ubuntu1_amd64.deb

After that, you can continue to fix other broken installs

sudo apt --fix-broken install
