本地Ubuntu服务器Ansible部署Apache报错：Failed to update apt cache

尝试在本地Ubuntu服务器上通过Ansible Playbook安装基础apache2，运行Playbook时出现以下错误：

PLAY [Ansible Playbook to Install and Setup Apache on Ubuntu] *******************************************************************************************************************

TASK [Gathering Facts] **********************************************************************************************************************************************************
ok: [localhost]

TASK [Install latest version of Apache] *****************************************************************************************************************************************
fatal: [localhost]: FAILED! => {"changed": false, "msg": "Failed to update apt cache: unknown reason"}

PLAY RECAP **********************************************************************************************************************************************************************
localhost                  : ok=1    changed=0    unreachable=0    failed=1    skipped=0    rescued=0    ignored=0 

Playbook中已将hosts变量设置为localhost，尝试了以下两个命令均无法解决问题：

• ansible-playbook playbook.yml --connection=local
• ansible-playbook playbook.yml

以下是详细的verbose报错信息：
