Either Apache or nginx on your install is interfering with lighttpd. Neither nginx nor Apache are supported servers, but there are some user solutions posted in Community Help here.

If you look in your log file at /var/log/lighttpd/error.log you will see the following (this is the output I see in your debug log, there may be more in the actual file):

Thanks!
How can I change it to the lighttpd webserver?

if that is the supported by default I can better use that also in mind for future updates

If you disable (and ideally remove) the other we servers, then you should be able to start lighttpd with

sudo service lighttpd start
