How to create a user with all root permissions without using sudo?

Question

linux

For example, I want to create an Admin user with all root rights and BLOCK the root user, I tried to do this with sudoers, but for example, apt must still be used with root rights, how else can I approach this issue.
Question if anything from a practical task ...

Answer 1

so no way ... the task is incorrectly formulated,
well, or ky0's answer is correct)

Answer 2

I suspect that "blocking root" in your case does not mean disabling the account, but something like turning off the ability to go as root via SSH.

Answer 3

I may be wrong, but if you create a user with the same id as root, then this user will be a full-fledged root in the system.
