Following packages have unmet dependencies: libopencv-dev

Hello, I;m a new Xavier NX user and installed jetpack4.4 and opencv 3.4 at /usr/local
Also I installed some package which required opencv lib exactly “highgui”.
However whenever i try to make It is not found although it is already installed,

So i tried “sudo apt install libopencv*” and i got

Could you clarify what you are trying to do? Are you trying to install opencv 3.4 manually but hit problem?

If so, why do you want to run apt install libopencv*? Do you have any expectation what it is going to install?

Did you already install opencv4.1.1 by jetpack?
