Query regarding opencv 4.5.4 debian package building

Hi Team,

I am trying to build a opencv4.5.4 debian package for jetson nano (arm 64) , but I am facing some issues during debain package installation. I need a confirmation that the debian package build is correct. I need this help from the community, and if you can share some resources to build a debian package that will be helpful.

- My end goal is to build a debian package like mentioned in this forum (https://forums.developer.nvidia.com/t/opencv-3-4-1-10-deb-packages-for-jetson-nano-w-cuda-gstreamer-v4l/79485).

- I have a bash script to install opencv4.5.4 for jetson nano platform obtained from (https://qengineering.eu/install-opencv-4.5-on-jetson-nano.html). I have attached the bash script below.

- I followed the tutorial to build a debian package from bash script (blog: https://blog.packagecloud.io/eng/2016/12/15/howto-build-debian-package-containing-simple-shell-scripts/). I have attached the debian package that I built below. (Apologies for the naming conventions).

Build failed:

$ sudo dpkg -i greetings_0.1-1_all.deb

(Reading database ... 183736 files and directories currently installed.)

Looking forward to hearing from you
