Troubleshooting Installation Issues with Nvidia-Cuda-Toolkit

When trying to install the Nvidia-cuda-toolkit on your Ubuntu system, you may encounter unmet dependencies errors that prevent successful installation. One common issue is when you try to install a package that requires specific versions of other packages.

In this case, the installation of Nvidia-cuda-toolkit depends on nvidia-cuda-dev version 9.1.85-3ubuntu1. However, your system is unable to find this package, leading to unmet dependencies errors.

Another issue you may encounter is when trying to install CUDA libraries that are required for specific applications. For instance, if you're trying to install a package that requires CUDA 10, but you only have CUDA 9 installed, you'll receive an error message indicating that the required version is not available.

To resolve these issues, it's essential to identify and fix unmet dependencies errors before proceeding with the installation. One way to do this is by running the command `apt -fix-broken install` without specifying any packages. This command will attempt to correct broken dependencies and install any missing packages.

Another approach is to manually install the required packages one by one, ensuring that each package's dependencies are met before moving on to the next one. In your case, you installed both the dev and runtime versions of CUDA, which may have caused further issues.

If you're still experiencing problems, it's a good idea to review the documentation for the specific package or application you're trying to install. For instance, the Nvidia-cuda-toolkit requires CUDA 10 and cuDNN. Make sure that these requirements are met before attempting to install the toolkit.

In conclusion, resolving installation issues with Nvidia-cuda-toolkit requires careful attention to unmet dependencies errors and a thorough understanding of the package's dependencies. By following these steps, you should be able to successfully install the required packages and avoid common pitfalls.
