Installing CUDA on Ubuntu 16.04 (unmet dependencies)

Question

I am a newbie to Ubuntu and am trying to install CUDA on it. I just couldn't do it.

I install Nvidia R390 driver (which is quite a hassel).

Then I followed the instruction at:

http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html

when I hit sudo apt-get install cuda

following errors pop up:

     Reading package lists... Done
    Building dependency tree       
    Reading state information... Done
    You might want to run 'apt-get -f install' to correct these.
    The following packages have unmet dependencies:
     cuda-cublas-dev-9-1 : Depends: cuda-cublas-9-1 (>= 9.1.85.3) but it is not installed
     cuda-cufft-dev-9-1 : Depends: cuda-cufft-9-1 (>= 9.1.85) but it is not installed
     cuda-curand-dev-9-1 : Depends: cuda-curand-9-1 (>= 9.1.85) but it is not installed
     cuda-cusolver-dev-9-1 : Depends: cuda-cusolver-9-1 (>= 9.1.85) but it is not installed
     cuda-cusparse-dev-9-1 : Depends: cuda-cusparse-9-1 (>= 9.1.85) but it is not installed
     cuda-libraries-9-1 : Depends: cuda-nvrtc-9-1 (>= 9.1.85) but it is not installed
                          Depends: cuda-nvgraph-9-1 (>= 9.1.85) but it is not installed
                          Depends: cuda-cusolver-9-1 (>= 9.1.85) but it is not installed
                          Depends: cuda-cublas-9-1 (>= 9.1.85) but it is not installed
                          Depends: cuda-cufft-9-1 (>= 9.1.85) but it is not installed
                          Depends: cuda-curand-9-1 (>= 9.1.85) but it is not installed
                          Depends: cuda-cusparse-9-1 (>= 9.1.85) but it is not installed
                          Depends: cuda-npp-9-1 (>= 9.1.85) but it is not installed
     cuda-npp-dev-9-1 : Depends: cuda-npp-9-1 (>= 9.1.85) but it is not installed
     cuda-nvgraph-dev-9-1 : Depends: cuda-nvgraph-9-1 (>= 9.1.85) but it is not installed
     cuda-nvrtc-dev-9-1 : Depends: cuda-nvrtc-9-1 (>= 9.1.85) but it is not installed
     cuda-toolkit-9-1 : Depends: cuda-nvml-dev-9-1 (>= 9.1.85) but it is not installed
     cuda-visual-tools-9-1 : Depends: cuda-nvml-dev-9-1 but it is not installed
    E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

So I use sudo apt-get -f install, but following errors occurred:

Can someone help? I am running out of ideas. Thanks!

• download the latest version from here

• then stop you X display manager (lightdm is default for ubuntu)

   sudo service lightdm stop 

• INSTALL DISPLAY DRIVER (recommended) AND CUDA TOOLKIT

   sudo chmod +x cuda_9.0_linux.run sudo ./cuda_9.0_linux.run 

• POST-INSTALL ( add these lines to the end of your .bashrc file )

   export CUDA_HOME=/usr/local/cuda-9.0 export LD_LIBRARY_PATH=${CUDA_HOME}/lib64:$LD_LIBRARY_PATH PATH=${CUDA_HOME}/bin:${PATH} export PATH 

• CUDNN INSTALL(optional)

  get the CUDNN stuff from HERE

   tar -xzvf cudnn-XYtgz cd cudnn-XY/cuda sudo cp -r * /usr/local/cuda-9.0 sudo ldconfig 

  just remember to check which versions of cuda and cudnn are supporterd by the tensorflow version you are going to install. ( for example cuda9.0, cudnn7 for tensorflow 1.7 which is the latest version when i write this answer)

I haven't replicated the problem but your trace suggests that the /boot partition is running out of space. Try clearing some old kernels, then re-run the command. Your installation should resume normally. I hope that helps :)
