Port 80 appears to already be in use.

This will show you what command is using port 80  
./discourse-setup: line 283: lsof: command not found

See [Run other websites on the same machine as Discourse](https://meta.discourse.org/t/17247)

If you are reconfiguring an already-configured Discourse, use

./launcher stop app

to stop Discourse before you reconfigure it and try again.
