What steps are necessary for correct installation of Ansible on a system?

The following steps are usually performed for correct installation of Ansible on a system:

1. Update the package list and install necessary dependencies (e.g., Python and pip).
2. Install Ansible via the system's package manager or using pip.
3. Verify the installation by running the command ansible --version.

Example for Ubuntu:

sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository --yes --update ppa:ansible/ansible
sudo apt install ansible
ansible --version

Or via pip:

pip install ansible
ansible --version

After installation, you can configure the inventory and check the connection to hosts.
