FAILED! => {"changed": false, "msg": "apt cache update failed"}

How would you fix this error with cache, mate?)
I've already added some vars to hosts file and main.yml.

# Example inventory that makes an alias for localhost that uses Python3
localhost-py3 ansible_host=localhost ansible_connection=local ansible_python_interpreter=/usr/bin/python3
 
# Example of setting a group of hosts to use Python3
[py3-hosts]
ubuntu18
 
[py3-hosts:vars]
ansible_python_interpreter=/usr/bin/python3

- name: Run apt upgrade
  apt:
    upgrade: "yes"
    update_cache: yes
    cache_valid_time: 432000
  async: 7200
  poll: 20
  notify: reboot

ansible-playbook provision.yml -l webservers -i hosts -u organic -vvv
