How do I completely wipe Cuda and CudNN off my ubuntu 16.04?

Question

Removing nvidia cuda toolkit and installing new one

Followed everything from the above link but I still have cuda and cuda-9.1 folder in my /usr/local/ directory?

Answer 1

The official NVIDIA CUDA installation guide gives a similar but more complete method:

To remove CUDA Toolkit:

$ sudo apt-get --purge remove "*cuda*" "*cublas*" "*cufft*" "*cufile*" "*curand*" "*cusolver*" "*cusparse*" "*gds-tools*" "*npp*" "*nvjpeg*" "nsight*" 

To remove NVIDIA Drivers:

$ sudo apt-get --purge remove "*nvidia*"

To clean up the uninstall:

$ sudo apt-get autoremove

(See here for more details: https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html)

Answer 2

Try these commands if you haven't already

sudo apt-get --purge -y remove 'cuda*'
sudo apt-get --purge -y remove 'nvidia*

after this I ran the command below and it did the trick for me

sudo apt-get autoremove --purge cuda
