I installed the following PPA:

deb http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu/ xenial main

performed an update but apt-get is unable to find a package that is listed. If you check here,


you'll see a number of nvidia-graphics-drivers-xyz available for xenial. However, apt-get doesn't recognize them at all.

Here is some information showing the state of my machine,

I'm suring that I'm missing something simple and obvious but I'm missing it. Packages are listed on the PPA website for xenial. I have the PPA installed and performed an update yet it's not finding the package.

I've looked at related posts but have not found a solution...

Anybody see the obvious that I'm missing?

[UPDATE]OS version information:

joehays@scylla:/etc$ cat os-release 
VERSION="16.04.6 LTS (Xenial Xerus)"
PRETTY_NAME="Ubuntu 16.04.6 LTS"
  • What is your Ubuntu version? Why do you have "(base) "? Is it a chroot or conda environment? – N0rbert May 22 '20 at 7:23
  • @N0rbert, yes, "(base)" is the active python virtual environment. It's irrelevant. I just deactivated it and reupdated and the problem persists. I've also updated the post with my OS version information. – Southern.Cross May 22 '20 at 13:38

The problem here is the following - the nvidia-graphics-drivers-430 is the name of source package, but the main binary is named simply nvidia-430 - check this page on PPA.

So you can use command below to install Nvidia 430:

sudo apt-get install nvidia-430

or install them using GUI from 5th tab of Software & Updates (software-properties-gtk) named Addtional Drivers.
