I suppose you are using the wrong filename.
Have you compared the command with the name of the file that you downloaded?
The filename of the latest version of the driver for the ZED Box is stereolabs-zedbox-duo_1.3.2-LI-MAX96712-all-ZEDBOX-L4T36.4.0_arm64.deb
So the command to install the driver is
sudo dpkg -i stereolabs-zedbox-duo_1.3.2-LI-MAX96712-all-ZEDBOX-L4T36.4.0_arm64.deb
If the name does not match, then you downloaded the wrong file again.
