Hi @prahalad12345 Are you attempting to install librealsense from Debian packages on a computer or computing device with an Arm processor please, such as a Raspberry Pi or Nvidia Jetson? And are you doing so with the instructions in the link below?

https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md

If you are using an Arm device, the Debian packages from this repository will not work with Arm as they require an x86 or x64 architecture processor, such as those used in laptop and desktop computers. Could you tell me which device you are using please (Pi, Jetson, etc) so that I can direct you to appropriate librealsense installation instructions for that device.

it an arm processor
