How can I revoke permission to set task to complete on a user role?

Question

I have a couple of people performing tasks. In order to manage everything we have appointed someone to oversee the work that has been done. He is the only one who should be able to set a task to "Complete". All the others should only be able to set a task to "To be reviewed".

How do I manage that in user roles?

I'm in a Next-Gen Project...

You don't do it in roles, you do it in the workflow.  Go to the project settings and pull up the issue type you want to do this with, near the top right, there's an "edit workflow" that takes you to a diagram of the flow.  Find the transition (arrow) that goes into "complete" and click on that to focus on it, then look for "rules" in the right hand side.  If you add a rule, it will ask you what type of rule you want - look for "restrict who can move an issue" and that will pop up a box asking you who you want to allow the transition to - you can name people, groups or project roles in there.
