Help and Support Raspberry Pi

I have the lastest Version of OSMC on my RPi3. The Webinterface from Kodi runs on Port 8080. If I install apache2 it wont start and /etc/init.d/apache2 status gives out this:

    root@pi:/# /etc/init.d/apache2 status
* apache2.service - LSB: Apache2 web server
   Loaded: loaded (/etc/init.d/apache2)

I found this: Apache2 faild every time - Raspberry Pi Forums
Looks like the same issue and with osmc too. But there isnt a solution. But maybe that can help you to support me.
Thanks for your help.

Kodi webserver runs on 80 by default.
Double check that, otherwise check Apache error log. That will show you what the problem is

Error file is empty and the Kodi Webserver runs on Port 8080

Try run the apache2 binary directly and you will soon see the problem
