Install Ansible on Ubuntu

Add the official APT repository of Ansible:

$ sudo apt-add-repository ppa:ansible/ansible

Add the public key:

$ curl -sL "" | sudo apt-key add

Update the list of packages and install Ansible on Ubuntu:

$ sudo apt update
$ sudo apt install ansible

Check the installed version of Ansible and the default location of ansible.cfg:

$ ansible --version

Now you can do a fast connection test from the command line to check if the Ansible can communicate with the remote hosts.

Test connection to a remote host using username and password-based authentication:

$ ansible -i <host>, all -u <username> -k -m ping

If you already have SSH-keys configured, you can test the connection as follows:

$ ansible -i <host>, all -u <username> -m ping

Note, that the comma after <host>, is mandatory, otherwise <host> is treated like a file name, that will cause the following errors:

[WARNING]: Unable to parse …/<host> as an inventory source
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match ‘all’
