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. 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. 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.
