Hi!  
I met a error when installing the SDK 3.5.0。  
my environment: cuda 10.2 ubuntu 18.04 package:ZED\_SDK\_Ubuntu18\_cuda10.2\_v3.5.0.run

The mistake shows:  
The following packages have unsatisfied dependencies:  
Libusb-1.0-0-dbg: dependency: libusb-1.0-0 (= 2:1.0.17-1ubuntu2), but 2:1.0.21-2 is about to be installed.

After that I install libusb-1.0-0=2:1.0.17-1ubuntu2 and libusb-1.0-0-dev, but it still shows this error. I don’t know how to solve it.  
Thanks!

Hi @wildpig888  
can you please provide more information (CPU, GPU, ecc) about the host system that you are using with the ZED2i?

Thank you
