For a long time, root was the default user on Linux, but it’s now disabled on most distributions. If like me, you were used to it, this article will answer your questions and guide you with the new best practice. I’ll also show you some workarounds if you really need “root”.
On Debian, using “sudo” is the recommended method to get administrator privileges with the main user, instead of using “root”. If needed, the “root” user can still be enabled by setting up their password.
Let’s start with a bit of theory, to give you the context, and then I’ll show you how to enable root if you really want it, either in a terminal or even for SSH usage.
