Installing ROS 2 via Debian Packages¶
Table of Contents
Debian packages for ROS 2 Rolling Ridley are currently available for Ubuntu Focal. The Rolling Ridley distribution will change target platforms from time to time as new platforms are selected for development. The target platforms are defined in REP 2000 Most people will want to use a stable ROS distribution.
Make sure you have a locale which supports
If you are in a minimal environment, such as a docker container, the locale may be something minimal like POSIX.
We test with the following settings.
It should be fine if you’re using a different UTF-8 supported locale.
sudo locale-gen en_US en_US.UTF-8 sudo update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8 export LANG=en_US.UTF-8
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'
Update your apt repository caches after setting up the repositories.
sudo apt update
Desktop Install (Recommended): ROS, RViz, demos, tutorials.
sudo apt install ros-rolling-desktop
ROS-Base Install (Bare Bones): Communication libraries, message packages, command line tools. No GUI tools.
sudo apt install ros-rolling-ros-base
Set up your environment by sourcing the following file.
If you installed
ros-rolling-desktop above you can try some examples.
In one terminal, source the setup file and then run a C++
source /opt/ros/rolling/setup.bash ros2 run demo_nodes_cpp talker
In another terminal source the setup file and then run a Python
source /opt/ros/rolling/setup.bash 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.
See the tutorials and demos for other things to try.
By default the RMW implementation
Fast RTPS is used.
Cyclone DDS is also installed.
To install support for
sudo apt update sudo apt install ros-rolling-rmw-connext-cpp # for RTI Connext (requires license agreement)
By setting the environment variable
RMW_IMPLEMENTATION=rmw_connext_cpp you can switch to use RTI Connext instead.
ros1_bridge as well as the TurtleBot demos are using ROS 1 packages.
To be able to install them please start by adding the ROS 1 sources as documented here.
If you’re using Docker for isolation you can start with the image
This will also avoid the need to setup the ROS sources as they will already be integrated.
Now you can install the remaining packages:
sudo apt update sudo apt install ros-rolling-ros1-bridge
The turtlebot2 packages are not currently available in Rolling.
If you would like to build your own packages, refer to the tutorial "Using Colcon to build packages".
