This configuration file works for Ubuntu 22.
Run sudo ls then run ansible-playbook server-config.yml to configure ssh access
and global installation on TelesCoop servers.
Then run ansible-playbook mail.yml to configure server mail
to use Mailgun.
The vault.key is required only because the smtp password for
mailgun is stored. If you don't need mail configuration, you
can remove/comment the line vault_password_file = vault.key
in ansible.cfg and it will stop complainig about not found
key file.
