3. Set the memory size (RAM) (at least 2 GB is recommended)(to green).

4. Set the size of the virtual hard disk (at least 25 GB is recommended) and click "Create".

Step 4: Install Ubuntu 20.04

1. After creating the virtual machine, select it from the list in VirtualBox and click "Start".

2. When prompted, choose the Ubuntu 20.04 ISO file you downloaded and click "Start".

3. Follow the on-screen instructions to install Ubuntu 20.04 on the virtual machine.

2. Add the ROS repository to your system:

   sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'

3. Add the ROS key:

   sudo apt install curl
   curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -

4. Update the package list:

   sudo apt update

5. Install the full version of ROS (Noetic):

   sudo apt install ros-noetic-desktop-full

• "If you get a problem like the one I have, go to step 6, solve the problem, and go back and complete the installation. If you don’t get a problem, complete the installation."
• Step 6: Problems installing ROS and their solutions -no error

7. Set up the ROS environment:

   echo "source /opt/ros/noetic/setup.bash" >> ~/.bashrc
   source ~/.bashrc

Congratulations! ROS is now successfully installed on Ubuntu 20.04 within VirtualBox. You can start using ROS to develop robotics applications.

Step 6: Problems installing ROS and their solutions

1. go to settings and go About and Software Updates

2. Make sure this setting is set

3. Go to (Terminal) and place these commands in this order

    sudo apt clean

    sudo apt autoclean
