I apologize, I am new to using Linux servers and commands. The app was not running, so I do:

```plaintext
./launcher start app
x86_64 arch detected. starting up existing container                          
+ /usr/bin/docker start app
app

```

After that:

`./launcher enter app`

And then, following your indications, first error:

```plaintext
sudo postgres            
sudo: postgres: command not found

```

If I type psql:

`psql: error: FATAL: database "root" does not exist`
