How To Fix NVIDIA Driver Installation Issues on Ubuntu 18.04

Ubuntu 1

In this article, we will walk you through the process of resolving issues related to the installation of NVIDIA drivers on the Ubuntu 18.04 operating system. We will provide step-by-step instructions using the terminal, and explain the purpose of each command to help you understand the process better.

Introduction

NVIDIA is a leading manufacturer of graphics processing units (GPUs), which are essential for tasks that require heavy graphics processing such as gaming, 3D modeling, and deep learning. Ubuntu 18.04, like other Linux distributions, supports NVIDIA GPUs, but sometimes, users may encounter issues when installing the drivers. This guide will help you troubleshoot and fix these issues.

Prerequisites

Before we begin, ensure that you have administrative (sudo) privileges to your Ubuntu 18.04 system.

Solution 1: Clean the Package Cache and Fix Broken Dependencies

Sometimes, the package cache or broken dependencies can cause issues with the NVIDIA driver installation. Here’s how to fix this:

  1. Open the terminal. You can do this by pressing Ctrl+Alt+T.
  2. Clean the package cache by running the following command:
sudo apt-get clean

This command cleans the local repository of retrieved package files left from previous installations.

  1. Next, fix any broken dependencies using this command:
sudo apt --fix-broken install

This command attempts to correct a system with broken dependencies in place.

  1. If the above steps don’t resolve the issue, you can try removing the problematic packages manually. For instance, to remove the libnvidia-gl-390 package, you would use:
sudo dpkg -r libnvidia-gl-390

This command removes the specified package from the system.

  1. After removing the problematic package, try installing the NVIDIA drivers again. For example, to install the nvidia-driver-390 and libvulkan1 packages, you would use:
sudo apt install nvidia-driver-390 libvulkan1

This command installs the specified packages.

Solution 2: Remove Diverted Packages

In some cases, diverted packages related to NVIDIA can cause installation issues. Here’s how to resolve this:

  1. Open the terminal.
  2. Run the following command to remove any diverted packages related to nvidia-340:
sudo dpkg-divert --list '*nvidia-340*' | sed -nre 's/^diversion of (.*) to .*/\1/p' | xargs -rd'\n' -n1 -- sudo dpkg-divert --remove

This command lists all diversions related to nvidia-340, then removes them.

  1. Run the sudo apt --fix-broken install command again to fix any broken dependencies.
  2. Finally, install the recommended NVIDIA drivers using the ubuntu-drivers devices and nvidia-settings commands.

Solution 3: Remove Specific Diversions

If the above solutions don’t work, you can try removing specific diversions. Here’s how:

  1. Open the terminal.
  2. Run the following command to remove the diversion for nvidia-340:
dpkg-divert --package nvidia-340 --remove /usr/lib/i386-linux-gnu/libGL.so.1

This command removes the specific diversion for nvidia-340.

  1. Repeat the above command for any other conflicting diversions.
  2. Try installing the NVIDIA drivers again.
