近一个月后我开始使用笔记本电脑了。访问localhost会给我以下错误：
apache2.service - LSB: Apache2 web server
Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled)

我正在使用Ubuntu 16.04以及以下Apache2版本：
Server version: Apache/2.4.18 (Ubuntu)
Server built: 2016-07-14T12:32:26
我尝试更改其他文章中提到的httpd.conf，但这没有帮助，我仍然继续得到此错误。任何帮助将不胜感激。
