我正在使用ansible部署网站。但我得到了这个错误：
fatal: [lxc-server]: FAILED! => {"failed": true, "msg": "The task includes an option with an undefined variable. The error was: [{u'authorized_keys': u'{{ delivery_authorized_keys }}', u'group': u'{{ magento_webserver_group }}', u'name': u'{{ magento_project_user }}'}]: {{ http_group_name }}: 'http_group_name' is undefinednnThe error appears to have been in '/home/jredor/projets/webstore/architecture/provisioning/provision.yml': line 32, column 7, but maynbe elsewhere in the file depending on the exact syntax problem.nnThe offending line appears to be:nnn - name: "Prepare the delivery_users object"n ^ herennexception type: <class 'ansible.errors.AnsibleUndefinedVariable'>nexception: [{u'authorized_keys': u'{{ delivery_authorized_keys }}', u'group': u'{{ magento_webserver_group }}', u'name': u'{{ magento_project_user }}'}]: {{ http_group_name }}: 'http_group_name' is undefined"}
我知道有一些东西没有定义，但问题是，它是由其他人开发的，应该可以完美地工作，而这个其他人已经不在了。这是规定。yml:

# Update permissions

错误在那里触发：
- name: "Prepare the delivery_users object"
set_fact: delivery_users="{{ tmp_delivery_users }}"
所以，正如我所说，我理解http_group_name是未定义的，但我如何定义它呢？如何调试？
我注意到http_group_name是在distro vars中定义的，其中每个distri都有一个yml文件。有CentOS-7、Debian-8、Debian-9、RadHat-7和Ubuntu-16.04。但我的发行版是Ubuntu 20.04。可能是问题吗？我应该创建一个Ubuntu-20.04.yml吗？感谢

我没有任何"；http_group_name"在这里。这是错误吗？我应该在那里定义它吗？如果是，我该怎么做？
问题出在发行版上。由于我在我的容器上使用debian 10，我在debian 9上做了一个新容器，它起了作用。
