Linux Distribution

Using pre-build packages

Intel® RealSense™ SDK 2.0 provides installation packages for Intel X86/AMD64-based Debian distributions in dpkg format for Ubuntu 16/18/20 LTS.
The Realsense DKMS kernel drivers package (librealsense2-dkms) supports Ubuntu LTS kernels 4.4, 4.8, 4.10, 4.13, 4.15, 4.18*, 5.0*, 5.3* and 5.4. Please refer to Ubuntu Kernel Release Schedule for further details.

Configuring and building from the source code

While we strongly recommend to use DKMS package whenever possible, there are certain cases where installing and patching the system manually is necessary:

  • Using SDK with non-LTS Ubuntu kernel versions: **4.16 **
  • Integration of user-specific patches/modules with librealsense SDK.
  • Adjusting the patches for alternative kernels/distributions.

The steps are described in Linux manual installation guide

Installing the packages:

  • Register the server's public key:
    sudo apt-key adv --keyserver --recv-key F6E65AC044F831AC80A06380C8B3A55A6F3EFCDE || sudo apt-key adv --keyserver hkp:// --recv-key F6E65AC044F831AC80A06380C8B3A55A6F3EFCDE In case the public key still cannot be retrieved, check and specify proxy settings: export http_proxy="http://<proxy>:<port>"
    , and rerun the command. See additional methods in the following link.

  • Add the server to the list of repositories:
    Ubuntu 16 LTS:
    sudo add-apt-repository "deb xenial main" -u
    Ubuntu 18 LTS:
    sudo add-apt-repository "deb bionic main" -u
    Ubuntu 20 LTS:
    sudo add-apt-repository "deb focal main" -u

  • Install the libraries (see section below if upgrading packages):
    sudo apt-get install librealsense2-dkms
    sudo apt-get install librealsense2-utils
    The above two lines will deploy librealsense2 udev rules, build and activate kernel modules, runtime library and executable demos and tools.

  • Optionally install the developer and debug packages:
    sudo apt-get install librealsense2-dev
    sudo apt-get install librealsense2-dbg
    With dev package installed, you can compile an application with librealsense using g++ -std=c++11 filename.cpp -lrealsense2 or an IDE of your choice.

Reconnect the Intel RealSense depth camera and run: realsense-viewer to verify the installation.

Verify that the kernel is updated :
modinfo uvcvideo | grep "version:" should include realsense string

Upgrading the Packages:

Refresh the local packages cache by invoking:
sudo apt-get update

Upgrade all the installed packages, including librealsense with:
sudo apt-get upgrade

To upgrade selected packages only a more granular approach can be applied:
sudo apt-get --only-upgrade install <package1 package2 ...>
sudo apt-get --only-upgrade install librealsense2-utils librealsense2-dkms

Uninstalling the Packages:

Important Removing Debian package is allowed only when no other installed packages directly refer to it. For example removing librealsense2-udev-rules requires librealsense2 to be removed first.

Remove a single package with:
sudo apt-get purge <package-name>

Remove all RealSense™ SDK-related packages with:
dpkg -l | grep "realsense" | cut -d " " -f 3 | xargs sudo dpkg --purge
