updateApt.yml

- name: APT Update  hosts: webservers  become: True  tasks:    - name: Update apt      apt:        update_cache: yes

error :

fatal: [testserver2]: FAILED! => {"changed": false, "failed": true, "msg": "Failed to lock apt for exclusive operation"}

Change the playbook as:

- name: APT Update  hosts: webservers  become: True  tasks:    - name: Update apt      apt:        update_cache: yes        cache_valid_time: 3600

and do this on target machine

sudo apt-get clean sudo apt-get update

this fixed it for me, running it on target machine
