They are installed. The issue is that they were configured not to be used, and now they are. I don't remember where the setting is but you decide whether to use nVidia drivers or not, even without uninstalling them. And this setting shouldn't be changed by the update: the fact that it is is a bug.

The nvidia source package produces two individual dkms packages: nvidia-340-updates, nvidia-340-updates-uvm. The problem is that the DKMS build of the nvidia-uvm module runs compile steps inside the nvidia modules build directory. This is violating the DKMS assumption that each module can be build independently (there is no way of describing cross-modules dependencies and even more important, the autoinstall step after a new kernel is installed will run the modules build in parallel). Since nvidia and nvidia-uvm are very dependent on each other the right course of action seems to be to combine both sources in one DKMS module that produces two kernel modules (this is supported by DKMS). For the transition this resulting dkms package needs to have a breaks/replaces for the nvidia-uvm package.
