Added graphics-drivers ppa, but no packages appear

I've tried to install the 396 drivers after doing...

sudo add-apt-repository ppa:graphics-drivers/ppa

...assuming that it allow me to install nvidia-graphics-drivers-396 or vulkan, but apt doesn't allow me to install either of those.

EDIT: Sorry for not providing much detail at all.

I'm using Ubuntu Budgie 18.04, and kernel 4.16.15-041615-generic.

I also have an Nvidia GeForce GTX 860M. This card is still technically supported by Nvidia.

It turns out that the package nvidia-driver-396 can be installed to get the 396 drivers. However, it's much easier to go into Software; in the menu, under Software and Updates > Additional Drivers, you can install nvidia-driver-396.

Did you run

apt-get update

at least once after the add of the PPA to your repository?

What I would do after that is a search to see what's available. Something like this:

apt-cache search nvidia | less

Then search for the packages as found on the PPA page. If you can't find them, then the install command won't work.
