Password Root Privleges

Good day everyone-
I'm looking for advice-
I have a couple of questions-
(1) I am trying to view videos on Knoppix 6.2 via websites ---youtube... any type of online website.
---it promps me to download adobe flash player---and provides several options --I don't know what one to choose
------yum for linux
------tr.gz for linux
-----.rpm for linux
-----.deb for ubuntu 8.0
-----APT for ubuntu 9.04
--I have tried them but keep running into my second issue when I down load the file and use kpackage to open and install - it says "the action you request needs root privileges -Please enter root's password.
I have gone in the terminal screen and reset/ changed the password to one that I would know and it did with no problems. I tried angain and it wouldn't work.
Also anybody have any ideas how to get the sound to work on email evolution

Thanks in advance
Jim

From the Start menu, choose Accessories, then Root Terminal. In that type:

Code:

---

aptitude update && aptitude install flashplugin-nonfree

---

When you reopen Iceweasel you should be able to view flash animation.

It's the .deb package you need. An alternative to the very good advice about aptitude given above is downloading the .deb package to the home directory, then open a terminal and issue

Code:

---

sudo dpkg -i <name of .deb package file>

---

The sudo command lets you run commands as root, without logging in as root.
