I can't install ar_track_alvar on ROS Noetic

I download ROS Noetic but when I paste this line on Terminal, it can't found.

$ sudo apt-get install ros-indigo-ar-track-alvar

How can I solve this problem?

As I know, this package is avaliable for Noetic but I can't install it.

I happened to do this just now so here's what worked for me:

  • Run git clone https://github.com/machinekoder/ar_track_alvar.git -b noetic-devel in your workspace (~/catkin_ws in my case)
  • Install a bunch of needed dependencies sudo apt-get install ros-noetic-cv-bridge ros-noetic-image-transport ros-noetic-pcl-conversions ros-noetic-pcl-ros ros-noetic-resource-retriever libtinyxml-dev -y

If the second one does not work for you, you might need to also run the following

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu `lsb_release -cs` main" > /etc/apt/sources.list.d/ros-latest.list'
sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654
sudo apt-get update

Finally run a catkin_build in your workspace and don't forget to source ~/catkin_ws/devel/setup.bash (or whatever your workspace is named)

That command is trying to install the package for Indigo, not Noetic. Make sure your package names include the ROS distro you’re targeting.

sudo apt install ros-noetic-ar-track-alvar

Edit based on comment: It does appear there is a noetic build for this package, but it doesn't look like it's officially tracked on the ROS wiki. If it isn't supplied via apt you will need to build the package from source. The Noetic source can be found here on GitHub.
