Trying to configure OpenVPN on a server, but encounter an error

To install Open-VPN on a server I followed these commands:

Install Ansible and Git:

sudo apt-get install -y python3-pip git rsync ansible

Clone this repository:

git clone https://github.com/d3vilh/openvpn-aws

Then enter the repository directory:

cd openvpn-aws

Install requirements:

ansible-galaxy collection install -r requirements.yml --force

If you see ansible-galaxy: command not found, you have to relogin and then try again.

Make copies of the configuration files and modify them for your environment:

yes | cp -p example.config.yml config.yml

Run the following command to add the docker group if it doesn't exist and add user to the docker group:

sudo groupadd docker

sudo usermod -aG docker $USER

Relogin now to apply group changes.

`Double check that ansible_user is correct for inventory.yml. Nee`d to run installtion on the remote server - follow the recomendations in config file.

`nano inventory.yml`, save the file - `Ctrl+O` and `Ctrl+X` to exit.

Run installation playbook:

sudo ansible-playbook main.yml

After following all instructions for installing OpenVPN, I encountered this error.

I've been trying different solutions to install OpenVPN, but I haven't been successful. I've searched online for instructions on using Docker files and changing parameters in the openvpn_ubuntu.yml file, but they haven't been helpful. Do you have any ideas on how I can properly install OpenVPN?

This is the line 37 to 40 of this file mentioned in the error:
