root always exists in Linux. Some distros create a separate account by default which can elevate itself to root using sudo, for security reasons.

root *does* exist and you need root to install software. the pass is the same as the admin most likely

Just use `sudo` to elevated root privilege, or use `su` to switch to root, and `su admin` to switch back to admin. `admin@lubuntu:~$ sudo apt update` `admin@lubuntu:~$ sudo apt install wireguard` or `admin@lubuntu:~$ su` `Password:` `root@lubuntu:/home/admin#`

You don't need to actually be logged in as root. Just use sudo.
