I downloaded a package of cudnn but it stops being installed.(Ubuntu 16.04)

AI & Data Science Deep Learning (Training & Inference) cuDNN

I typed a command and ran it but it stops being installed.

sudo dpkg -i libcudnn7_7.0.5.15-1+cuda9.0_amd64.deb
(Reading database … 243130 files and directories currently installed.)

and comes back to command mode. I tried several other versions of cudnn(even the recentest one)
, but I cannot find the files from my cuda directory. What should I do?

I also met this problem. Installed CUDA and Driver are 10.1 and 418.87, and I tried to install cuDNN 7.64 and 7.65 via runtime deb.
