No official support for kernel 5.15 is available from Intel Realsense.
A workaround is to use a community contribuition.
Unplug your realsense camera.
To install just:
wget https://github.com/mengyui/librealsense2-dkms/releases/download/initial-support-for-kernel-5.15/librealsense2-dkms-dkms_1.3.14_amd64.deb
Then:
sudo dpkg -i librealsense2-dkms-dkms_1.3.14_amd64.deb
rm librealsense2-dkms-dkms_1.3.14_amd64.deb
Now your kernel is patched with realsense.
Verify that the kernel is updated :
modinfo uvcvideo | grep "version:"
should include realsense
string.
Proceed installing all other realsense packages.
