How to create a superuser in Kubuntu?

[Knapp]

The GUI or Graphical User's Interface is just a layer on top of the
CLI or Command Line Interface. The graphics are great for making the
system easy to use but to really understand why the GUI is the why the
GUI is you will do well to understand the CLI commands.

There is a free book called Rutebook that you can install but you can
also read it here.

This chapter of the rutebook has all the details about this threads subject.

The basic answer to this question is that each user belongs to groups
and each group has commands it can use. You must have your user join
the group with the rights to use sudo.  I think that is admin.
