问题描述
我正在使用 Ubuntu pro 18.04 LTS 部署 openstack Stein。
我在控制器节点上部署了 Horizon 服务，以便使用此 article 控制所有 Openstack 组件
但是当请求 apache2 http 服务器时。我处理此错误消息：
public class Personviewmodel
{
public Personviewmodel(){
People=new CustomObservableCollection<Person>();
}
private void AddPerson(){
People.Add(new Person(){
FirstName="John",LastName="Doe",Age=20
});
}
private void UpdatePerson(){
var person=People.Where(...).FirstOrDefault();
person.Age=25;
People.Refresh(person);
}
public CustomObservableCollection<Person> People { get; set; }
}
打开apache2日志文件时：
500 Internal Server Error
我发现以下内容：

什么是修复？
解决方法
