Ubuntu install of ROS Noetic
The ROS build farm builds Debian packages for several Ubuntu platforms, listed below. These packages are ready to use so you don't have to build from source. You can check the status of individual packages here.
Note that there are also packages available from Ubuntu upstream. Please see UpstreamPackages to understand the difference.
If you rely on these packages, please support OSRF.
These packages are built and hosted on infrastructure maintained and paid for by the Open Source Robotics Foundation, a 501(c)(3) non-profit organization. If OSRF were to receive one penny for each downloaded package for just two months, we could cover our annual costs to manage, update, and host all of our online services. Please consider donating to OSRF today.
Configure your Ubuntu repositories
Configure your Ubuntu repositories to allow "restricted," "universe," and "multiverse." You can follow the Ubuntu guide for instructions on doing this.
Setup your sources.list
Setup your computer to accept software from packages.ros.org.
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
Source Debs are also available
Set up your keys
sudo apt install curl # if you haven't already installed curl curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -
First, make sure your Debian package index is up-to-date:
sudo apt update
Now pick how much of ROS you would like to install.
Desktop-Full Install: (Recommended) : Everything in Desktop plus 2D/3D simulators and 2D/3D perception packages
sudo apt install ros-noetic-desktop-full
or click here
Desktop Install: Everything in ROS-Base plus tools like rqt and rviz
sudo apt install ros-noetic-desktop
or click here
ROS-Base: (Bare Bones) ROS packaging, build, and communication libraries. No GUI tools.
sudo apt install ros-noetic-ros-base
or click here
There are even more packages available in ROS. You can always install a specific package directly.
sudo apt install ros-noetic-PACKAGEe.g.
sudo apt install ros-noetic-slam-gmapping
To find available packages, see ROS Index or use:
apt search ros-noetic
You must source this script in every bash terminal you use ROS in.
It can be convenient to automatically source this script every time a new shell is launched. These commands will do that for you.
If you have more than one ROS distribution installed, ~/.bashrc must only source the setup.bash for the version you are currently using.
echo "source /opt/ros/noetic/setup.bash" >> ~/.bashrc source ~/.bashrc
echo "source /opt/ros/noetic/setup.zsh" >> ~/.zshrc source ~/.zshrc
Dependencies for building packages
Up to now you have installed what you need to run the core ROS packages. To create and manage your own ROS workspaces, there are various tools and requirements that are distributed separately. For example, rosinstall is a frequently used command-line tool that enables you to easily download many source trees for ROS packages with one command.
To install this tool and other dependencies for building ROS packages, run:
sudo apt install python3-rosdep python3-rosinstall python3-rosinstall-generator python3-wstool build-essential
Before you can use many ROS tools, you will need to initialize rosdep. rosdep enables you to easily install system dependencies for source you want to compile and is required to run some core components in ROS. If you have not yet installed rosdep, do so as follows.
sudo apt install python3-rosdep
With the following, you can initialize rosdep.
sudo rosdep init rosdep update
Now, to test your installation, please proceed to the ROS Tutorials.
