CUDA is a parallel computing platform and application programming interface (API) model created by Nvidia. I am supposed to install this package in my system.

Download Packages

The official downloading page for CUDA is https://developer.nvidia.com/cuda-downloads. Currently, the latest version of the CUDA is 9.2. We can chose the corresponding packages.

Since there is no package for 18.04, I tried to use 17.10, hope it works fine.

Error and Solution

An error comes here:

Unpacking nvidia-396 (396.44-0ubuntu1) ...
dpkg: error processing archive /var/cache/apt/archives/nvidia-396_396.44-0ubuntu1_amd64.deb (--unpack):
 trying to overwrite '/usr/lib/x86_64-linux-gnu/libGLX_indirect.so.0', which is also in package libglx-mesa0:amd64 18.0.5-0ubuntu0~18.04.1
Errors were encountered while processing:
 /var/cache/apt/archives/nvidia-396_396.44-0ubuntu1_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

This error message terminated the installing process, and make apt command out of order as follow:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 cuda-drivers : Depends: nvidia-396 (>= 396.37) but it is not installed
 libcuda1-396 : Depends: nvidia-396 (>= 396.37) but it is not installed
 nvidia-396-dev : Depends: nvidia-396 (>= 396.37) but it is not installed
 nvidia-opencl-icd-396 : Depends: nvidia-396 (>= 396.37) but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Found a solution here

We can fix the problem using command:

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

I tried to spread this solution in popular threads so it might be easier to find it :)

Another thought that came to me – make a backup (snapshot) of my working system before I started to install Cuda :)

    @illia Nice! Actually I searched the solution for a long time as well.

    Besides, you probably need to keep the command since it may required in the future when updating the packages.
