Can't fetch OpenCV dependency - Jetpack 3.3 Installation

I’m installing Jetpack 3.3,

I installed OS,driver-CUDA-CUDNN via jetpack but when i am coming opencv installing step, such occurs occuring, normally its more longer error-fetch fails but giving brief version:

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

Because I installed everything for tensorrt-opencv-visionworks; I try to install via Build OpenCV on the NVIDIA Jetson TX2 - JetsonHacks

I did before many times from this link, it is so easy but it gives the same error.

What I tried:

Changing server from Software Updates
Changing sources.list file
A few solutions find from internet for failed to fetch error.

Any help would be appricated because I’m deeply stuck :(

Splendor027,

Sorry for late reply. Does this error happen only when you install jetpack3.3 opencv? How about cuda and cudnn?

I saw your reply soon, sorry for late reply too. CUDA and CUDNN is installed and i.e I can check CUDA with nvcc --version. But I can’t install OpenCV
