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.
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
