You will need to be root to create this new user. Once the user has sudo access they will have the same rights as the root user
1. Create the user
When you create the user you get this output.
Adding user `kmarquis' ... Adding new group `kmarquis' (1001) ... Adding new user `kmarquis' (1001) with group `kmarquis' ... Creating home directory `/home/kmarquis' ... Copying files from `/etc/skel' ...

[Y/n] y
2. Grant them sudo access by either:
a) usermod -G sudo kmarquis
look for the line
root (ALL=ALL:ALL) ALL
kmarquis (ALL=ALL:ALL) ALL
Hit Ctrl + X then Enter.
Now with whatever method used, the user will have root privileges via sudo. If you need to make any changes that require root access, you just need to enter sudo before the command. You will be prompted for your password before the command is run
[email protected]:~$ sudo apt-get update [sudo] password for kmarquis:
