NCS2 on Ubuntu-VirtualBox

416 Views

Hello,
I have Ubuntu 18 installed on VirtualBox with a connected NCS2 device. While I could run NCS2's demo on get-started page successfully, when I go to run another intel's NCS2 demo, which is in python on this page, I get below error:

.....

Do you have any idea what is wrong?
