I am trying to copy following files into the CUDA Toolkit directory, and change the file permissions. However I couldn't get permission allow CUDA. I tried many methods like chmod but it does not work for ubuntu 18.04.

$ sudo cp cuda/include/cudnn.h /usr/local/cuda/include
$ sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64
$ sudo chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*

One possible reason chmod do not work is UMASK. Try the command on this way:

sudo bash -c "umask=022 chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*"
