Grazie! Ho eseguito `discourse-setup` come root, e ha fatto molte cose, ma alla fine quando ha provato ad avviare discourse, la porta 80 sembrava già occupata.

```plaintext
/usr/bin/docker: Error response from daemon: driver failed programming external connectivity on endpoint app (5274a3306f48252a89b4fe81103ebe252645b91f15fa205319451aa5bf6c79d7): Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use.
==================== END REBUILD LOG ====================
Failed to rebuild app.

Checking your domain name . . .

```

E ha detto che non è riuscito. Mi stavo chiedendo se avrei dovuto usare un account utente diverso invece di root? O se c’è qualche processo che potrei terminare prima?
