Fixing Broken apt-get after Failed CUDA Installation

Ubuntu 15

In the world of Ubuntu, sometimes installations don’t go as planned and you end up with a broken system. One such scenario is a failed CUDA installation, which can result in a broken apt-get package manager. This article will guide you through the process of fixing the apt-get package manager after a failed CUDA installation.

Quick Answer

To fix a broken apt-get after a failed CUDA installation, you can try forcing the overwrite of conflicting files during package installation using the command sudo apt-get -o Dpkg::Options::="--force-overwrite" install --fix-broken. Alternatively, you can remove all CUDA-related packages using sudo apt-get remove --purge cuda-* libcuda* nvidia*. If these solutions do not work, it is recommended to consult official documentation or seek further assistance.

Understanding the Issue

The problem typically arises when installing nvidia-396 as part of the CUDA installation on Ubuntu 18.04. This can lead to conflicts with the package libglx-mesa0:amd64, causing the apt-get package manager to break. As a result, you may encounter unmet dependencies errors when trying to install other packages like git. The common solution of running sudo apt --fix-broken install often fails to resolve the issue.

Solutions

Force Overwrite During Package Installation

The first solution is to force the overwrite of conflicting files during package installation. This can be achieved by running the following command:

sudo apt-get -o Dpkg::Options::="--force-overwrite" install --fix-broken

In this command, -o Dpkg::Options::="--force-overwrite" instructs apt-get to overwrite the conflicting files, while install --fix-broken attempts to correct a system with broken dependencies in place.

Remove CUDA and Related Packages

Another solution is to remove all CUDA-related packages. This can be done using the following command:

sudo apt-get remove --purge cuda-* libcuda* nvidia*

In this command, remove --purge removes the packages along with their configuration files, while cuda-* libcuda* nvidia* specifies the packages to be removed.

Alternatively, you can remove specific packages like cuda-drivers, libcuda*, cuda-runtime*, cuda-8-0, cuda-demo* using the command:

sudo apt-get remove --purge cuda-drivers libcuda* cuda-runtime* cuda-8-0 cuda-demo*

After removing the packages, you can try reinstalling them or proceed with other package installations.

Remove All Installed Packages in a Single Command

If you want to remove all installed CUDA-related packages in one go, you can use the following command:

sudo apt-get remove --purge nvidia* cuda-drivers libcuda1-396 cuda-runtime-9-2 cuda-9.2 cuda-demo-suite-9-2 cuda

This command removes all installed CUDA-related packages in one go.

Conclusion

While the solutions provided in this article focus on fixing the broken apt-get package manager, they do not address the installation of CUDA itself. Some users have reported success with these solutions, while others have encountered further issues during reinstallation. It’s also worth noting that some users have switched to Ubuntu 16.04 to successfully install CUDA, indicating that compatibility issues may exist with Ubuntu 18.04.

If the provided solutions do not resolve the issue, it is recommended to consult official documentation or seek further assistance. Always remember to backup your data before making significant changes to your system.

What should I do if running `sudo apt-get -o Dpkg::Options::=”–force-overwrite” install –fix-broken` doesn’t fix the issue?

If running sudo apt-get -o Dpkg::Options::="--force-overwrite" install --fix-broken doesn’t fix the issue, you can try removing all CUDA-related packages using the command sudo apt-get remove --purge cuda-* libcuda* nvidia*. After removing the packages, you can try reinstalling them or proceed with other package installations.

Can I remove specific CUDA-related packages instead of all of them?

Yes, you can remove specific CUDA-related packages using the command sudo apt-get remove --purge cuda-drivers libcuda* cuda-runtime* cuda-8-0 cuda-demo*. This command removes the specified packages along with their configuration files.

Is it possible to remove all installed CUDA-related packages in one go?

Yes, you can remove all installed CUDA-related packages in one go using the command sudo apt-get remove --purge nvidia* cuda-drivers libcuda1-396 cuda-runtime-9-2 cuda-9.2 cuda-demo-suite-9-2 cuda.

Are these solutions guaranteed to fix the broken apt-get after a failed CUDA installation?

While these solutions have worked for some users, they may not work for everyone. There can be additional factors or compatibility issues that can affect the success of the solutions. It is recommended to consult official documentation or seek further assistance if the provided solutions do not resolve the issue.

Should I backup my data before attempting these solutions?

Yes, it is always recommended to backup your data before making significant changes to your system. This ensures that you have a copy of your important files in case anything goes wrong during the process.
