While trying to host a website to control GPIO over flask and Apache I am now receiving the error that 'Failed to start The Apache HTTP Server'. Some googling suggested that this might happen if other servers are listening on port 80 so I did
sudo ss -ntlp 'sport = 80' and returned two, both of which were lighttpd.
sudo service apache2 restart is what I executed when I first received this error; I was able to get the 'It Works!' page when I first instlled Apache.
How can I disable/turn off these servers using port 80?
