Ubuntu and most of it's variants don't /use/ a root password though it
can be set if you really want. The root password is not set by default
for security reasons. The effect is that if an attacker attempts to log
in as root, they will have no success no matter how many times they try
because the root user is not /able/ to log in directly...
The proper method for Ubuntu / Kubuntu / etc. is to log in as an admin
enabled user - usally the user that was first set up - and use the
command line as such:
# sudo <whichever command/binary you want to use>
The system will prompt you for the user's password. The password is
hidden - in fact, no characters of any sort are displayed, so be careful
typing the user's password. If they are set up as an admin and are also
in the "sudoer" file, then the application will(should) execute as root.
A neat little trick I use to keep from having to type sudo all the time
is to run:
# sudo su -
It's a neat trick, but don't get in the habit of doing it all the time -
it's bad muju.
