Problem making server blocks on ubuntu 18.04

hello i am trying to make a register using this tutorial however every time i go to check if it is running with ln -s /etc/nginx/sites-available/create /etc/nginx/sites-enabled it responds with ln: failed to create symbolic link ‘/etc/nginx/sites-enabled/create’: File exists

Sorry kinda late but what that response is telling you is that the sym link already exists.

If you want to create a new one, either remove the current one or rename the one you are creating (as long as it doesn’t override with the one that already exists).

rm /etc/nginx/sites-enabled/create

then rerun

ln -s /etc/nginx/sites-available/create /etc/nginx/sites-enabled
