Playbook won't run

[Mike-Zelixon]

Hi, I'm very new to Ansible and I installed this repo to harden a Ubuntu VM.
However, I keep getting an error every time I try to run a playbook.
For instance, when I run "ansible-playbook -i hosts main.yml" i get an error:

[WARNING]: Unable to parse /etc/ansible/CIS-Ubuntu-20.04-Ansible/tasks/hosts 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'
[DEPRECATION WARNING]: 'include' for playbook includes. You should use 'import_playbook' instead. This feature will be removed in version 2.12. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
ERROR! 'block' is not a valid attribute for a Play

The error appears to be in '/etc/ansible/CIS-Ubuntu-20.04-Ansible/tasks/section_1_Initial_Setup.yaml': line 6, column 3, but may be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

# server. If this filesystem type is not needed, disable it.
- name: 1.1.1.1 Ensure mounting of cramfs filesystems is disabled
  ^ here

Can you please tell me what I'm doing wrong? I will highly appreciate it.

You must select a inventory host (the host you want to apply the changes to it)
