Hey Nvidia-developers!
I recently tried using virtual CAN bus in Docker container but failed:
nvidia@TEGRA-A:~$ modprobe vcan
nvidia@TEGRA-A:~$ docker container run --cap-add=NET_ADMIN -it --rm ubuntu:20.04 bash

Is there any chance to fix this error?
Dear @kamelusz,
Could you confirm the used platform and software version?
Dear, @SivaRamaKrishnaNV, thank you for your answer!

nvidia@SIM-11-A:~$ cat /usr/share/drive/welcome/Welcome\ to\ DrivePX.html | grep "Software Release"
<title>NVIDIA DRIVE PX 2 (5.0.10.3 Software Release) | NVIDIA</title>
<div class="headersubtext"><b>Autonomous Vehicle Platform</b><br /><i>5.0.10.3 Software Release</i></div>
But I do not quite understand what you mean by “platform version”. Can you tell me how to find out the platform version?
