I hit on this same problem, on an Ubuntu 17 VM.

Any idea how to disable the default application on port 80?

A list of commands to type will be nice, as it has been decades since I administered a Unix/Linux machine…

I used `apt-get remove` to remove `apache*`, `nginx*` and `lighttpd`, but it still says the port is in use.

**EDIT** : Got it to work. Turns out tcp6 was still listening on port 80. Rebooting the VM made it go away, and I was successful in installing Discourse. Thanks!
