4. 4. Adding ROS Repo

   Then to Add ROS Repository for Ubuntu
   For Ubuntu 22.04/23.10 based Desktops, and so also for: Mint 21.x, Elementary OS 7.x, Zorin OS 17.x, Bodhi 7.x, Lite 6.x… Play:

   echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu jammy main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null

   So for Ubuntu 20.04/21.04 based Desktops, and so also for: Mint 20.x, Elementary OS 6.x, Zorin OS 16.x, Bodhi 6.x, Lite 5.x… Run:

   echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu focal main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null

   Instead, for Ubuntu 18.04, Mint 19.x, Elementary OS 5.x, Zorin OS 15.x, Bodhi 5.x, Lite 4.x… Play:

   echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu bionic main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null

5. 5. Adding ROS GPG Key

   Again to Add ROS GPG Signature Key
   Simply play:

   sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key  -o /usr/share/keyrings/ros-archive-keyring.gpg

   In case, to Install cURL:

   sudo apt install curl

6. 6. Refreshing Ubuntu Repo Sources

   Next to Refresh Ubuntu Apt Repository Sources
   Play:

   sudo apt update

   But in case of Not found issue for the Non LTS Releases then you should try to amend the Repo Manualli like:

   sudo nano /etc/apt/sources.list.d/ros2.list

   And setting to the nearest LTS one. So for instance on Ubuntu 21.10 try to amend “impish” in “jammy”!
   Last, Update the Apt Sources again.

7. 7. Installing ROS on Ubuntu
