One issue is trying to create a user to run services under, but not knowing how to give it permission to access what it needs (while also not entirely sure what it should/shouldn’t have permissions for).
Or just generally managing file permissions. I understand using chmod in a very basic capacity with a few letter arguments like +r, but then you toss in numbers (chmod 777, wut?) and I get lost.
In addition to what other posters said, some distros allow you to add a user to the “sudo” group (as a secondary group assignment; don’t make it their primary) to allow them sudo access.
How do I manage what users can use sudo?

Edit your /ect/sudoers file using visudo
