You're reading the documentation for a version of ROS 2 that has reached its EOL (end-of-life), and is no longer officially supported. If you want up-to-date information, please have a look at Iron.
Installing ROS 2 on Linux
This page explains how to install ROS 2 on Linux from a pre-built binary package.
The pre-built binary does not include all ROS 2 packages. All packages in the ROS base variant are included, and only a subset of packages in the ROS desktop variant are included. The exact list of packages are described by the repositories listed in this ros2.repos file.
There are also Debian packages available.
We support Ubuntu Linux Bionic Beaver (18.04) and Ubuntu Xenial Xerus (16.04) on 64-bit x86 and 64-bit ARM.
Note: Ardent and beta versions supported Ubuntu Xenial Xerus 16.04.
You will need to add the ROS 2 apt repositories to your system. To do so, first authorize our GPG key with apt like this:
sudo apt update && sudo apt install curl gnupg2 lsb-release
curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -
And then add the repository to your sources list:
sudo sh -c 'echo "deb [arch=$(dpkg --print-architecture)] http://packages.ros.org/ros2/ubuntu $(lsb_release -cs) main" > /etc/apt/sources.list.d/ros2-latest.list'
Download the latest package for Linux; let’s assume that it ends up at
Note: there may be more than one binary download option which might cause the file name to differ.
mkdir -p ~/ros2_eloquent cd ~/ros2_eloquent tar xf ~/Downloads/ros2-eloquent-linux-x86_64.tar.bz2
sudo apt update
sudo apt install -y python-rosdep
sudo rosdep init
Set your rosdistro according to the release you downloaded.
rosdep install --from-paths ros2-linux/share --ignore-src --rosdistro eloquent -y --skip-keys "console_bridge fastcdr fastrtps libopensplice67 libopensplice69 osrf_testing_tools_cpp poco_vendor rmw_connext_cpp rosidl_typesupport_connext_c rosidl_typesupport_connext_cpp rti-connext-dds-5.3.1 tinyxml_vendor tinyxml2_vendor urdfdom urdfdom_headers"
Optional: if you want to use the ROS 1<->2 bridge, then you must also install ROS 1. Follow the normal install instructions: https://wiki.ros.org/melodic/Installation/Ubuntu
sudo apt install -y libpython3-dev python3-pip
pip3 install -U argcomplete
If you would like to use another DDS or RTPS vendor besides the default, eProsima’s Fast RTPS, you can find instructions here.
Set up your environment by sourcing the following file.
In one terminal, source the setup file and then run a C++
ros2 run demo_nodes_cpp talker
In another terminal source the setup file and then run a Python
ros2 run demo_nodes_py listener
You should see the
talker saying that it’s
Publishing messages and the
I heard those messages.
This verifies both the C++ and Python APIs are working properly.
Continue with the tutorials and demos to configure your environment, create your own workspace and packages, and learn ROS 2 core concepts.
The ROS 1 bridge can connect topics from ROS 1 to ROS 2 and vice-versa. See the dedicated documentation on how to build and use the ROS 1 bridge.
The default middleware that ROS 2 uses is
Fast-RTPS, but the middleware (RMW) can be replaced at runtime.
See the tutorial on how to work with multiple RMWs.
Troubleshooting techniques can be found here.
If you installed your workspace with colcon as instructed above, “uninstalling” could be just a matter of opening a new terminal and not sourcing the workspace’s
setupfile. This way, your environment will behave as though there is no Eloquent install on your system.
If you’re also trying to free up space, you can delete the entire workspace directory with:
rm -rf ~/ros2_eloquent
