Hi there,

I am using ROS noetic on a ubuntu 20.04.1.

I am new to ROS and I am so confused about the package installation. For example, if I want to install the robot localization package, Do I just git clone it using the following command into my workspace?

$git clone -b noetic-devel https://github.com/cra-ros-pkg/robot_localization.git

I notice that package can be install through apt, but how can I know that apt command for the package I want?

sudo apt-get install ros-neotic-robot-localization

Usually, I do sudo apt-get install ros-neotic-robot and then search the available packages using tab.

See #q320046 for a related Q&A.

Summarising: do not build from source, unless there is an absolute need.

You can check if a specific package is released for a specific distro using the repositories.ros.org Status Pages. Choose the appropriate distro and architecture. I.e. for Noetic, go for ros_noetic_default. Then you can search if a package is released and which version has been synced to which package repository (testing, main).

To install packages, basically what @praskot said, is: sudo apt install ros-<DISTRO>-<PKG> with all underscores in the package name converted to dashes -.

If you want to build a package from source, you need to follow the following steps -

  • Clone the package to your catkin workspace
  • Install all the requisite dependencies using rosdep (link)
  • Build your package (using catkin build or catkin_make command)
  • Source your catkin workspace (using source ~/catkin_ws/devel/setup.bash)

Yeah, I think you can clone a repository and use on your workspace:

catkin_make

maybe someone has a more complete answer, I'm also new in ROS.
