I entered the wrong admin email address during initial setup

You can change default admin email address in app.yml file as below

After that you will need to enter your discourse folder, type out:

cd /var/discourse

then:

nano containers/app.yml

That’s it! Just make/edit your changes, then do:

git pull
./launcher rebuild app

You’re good to go!
