Issue Description

The current pre-release (v.2.56.1) claims to support Ubuntu 24.04 with kernel 6.8. However, when I tried to install it on my Ubuntu 24.04 with kernel 6.8 it fails when running the ./scripts/patch-realsense-ubuntu-lts-hwe.sh script with:
Unsupported distribution noble, kernel version 6.8.0-41-generic . The patches are maintained for Ubuntu 16/18/20 LTS

There is an open PR draft #13090 which addresses part of the issue, however it also did not work on my machine since ../scripts/realsense-metadata-noble-master.patch is missing.

Hi @SammyRamone Some changes have just been made today in a PR at #13236 (comment) that include updates of kernel 6.8 support and the manual patch script for Ubuntu 24 support.

aa0be52 highlights in green the update made to the patch script.

Thanks for the quick reply :)
Yes, you are right, the mentioned PR resolves this issue. I think I did not find it due to searching for "24.04" and not for "noble".
As soon as this PR is merged, this issue can be closed.

Ok, it seems that i'm not the only one who meets this problem: ./scripts/patch-realsense-ubuntu-lts-hwe.sh Unsupported distribution noble, kernel version 6.8.0-41-generic . The patches are maintained for Ubuntu 16/18/20 LTS, i wonder when will the bug-fixed librealsense sdk version released?

[IRONCROWY]

Oh, i found this modified branch working, nice, https://github.com/IntelRealSense/librealsense/tree/aa0be527737a90728d65447054d34294ebb547b6

There is one more problem is that, this librealsense version is 2.56.0, which is not compatiable with the latest realsense-ros version.

  Could not find a configuration file for package "realsense2" that is
  compatible with requested version "2.56.1".

  The following configuration files were considered but not accepted:

    /usr/local/lib/cmake/realsense2/realsense2Config.cmake, version: 2.56.0

CMake Error at CMakeLists.txt:126 (message):

   Intel RealSense SDK 2.0 is missing, please install it from https://github.com/IntelRealSense/librealsense/releases```

Hi @IRONCROWY Are you attempting to install the ROS wrapper from packages with a command such as sudo apt install ros-humble-realsense2-* please?

If you are, have you tried building the wrapper from source code with colcon build for use with your 2.56.0 librealsense version?

Hello, we are also using realsense, we have new machines we would like to use with kernel 6.8 so we are hitting this same issue.

Oh, my ros2 version is jazzy, so, emmm, humble version cannot be installed, (maybe i should sudo apt install ros-jazzy-realsense2-*?, this command seems okay and the camere node does woking) this failure just happened when using colcon build the realsense-ros using 2.56.0 librealsense.

By the way, at first i use the 2.56.1 beta librealsense because it supports ubuntu 24 but actually not, so i applied [#13236 ] to install librealsense and eventually i saddly found that its version is 2.56.0......

Ubuntu 24.04 / Kernel 6.8 users can try building the librealsense SDK from source code with CMake with the RSUSB Backend method. RSUSB bypasses the kernel and so is not dependent on a particular Linux version or kernel version and does not require a patch script to be applied to the kernel.

A RealSense user at #13065 (comment) succeeded with an RSUSB source code build on Ubuntu 24.04.

Instructions for an RSUSB installation can be found at #9931 (comment)

@MartyG-RealSense Thanks, both the sdk and ros are working after i remove all the old sdk and ros then reinstall them using RSUSB installation on Ubuntu 24.04.

[MartyG-RealSense]

@IRONCROWY That's great to hear that an RSUSB build on 24.04 succeeded for you!

The kernel 6.8 / Ubuntu 24.04 support updates in PR #13236 have now been merged into the development branch of the librealsense SDK.
