네, `./launcher start app`을 실행하려고 했는데 계속 다음과 같은 오류가 발생하고 있습니다:

```plaintext
root@Roblox-Development:/var/discourse# ./launcher start app

starting up existing container
+ /usr/bin/docker start app
Error response from daemon: driver failed programming external connectivity on endpoint app (73771b238a3c9cdb51c4976f9548e695f4d1a9b0a4605c33eb3d857a8206cffc): Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use
Error: failed to start containers: app

```

이 문제를 해결할 수 있는 방법이 있을까요?

추가 정보:

저는 다음 두 명령어만 실행했습니다.

```plaintext
sudo add-apt-repository ppa:nginx/stable -y
sudo apt-get update && sudo apt-get install nginx

```
