How to install flash player with Ubuntu?

We installed Ubuntu v9.04.  When we tried to go to youtube - it said we needed flash player.  Ok.  So we downloaded a package from adobe's site and followed instructions.  But every method failed as you can see below.  Are we doing something wrong?  

alex@alinux:/tmp$ ls -l
total 4016
-r-------- 1 alex alex    4368 2009-07-01 19:40 adobe-release-i386-1.0-1.noarch.rpm
-r-------- 1 alex alex 4065576 2009-07-01 20:03 flash-plugin-10.0.22.87-release.i386.rpm


But then ran into errors with every method of installing:
alex@alinux:/tmp$ rpm -Uvh adobe-release-i386-1.0-1.noarch.rpm

easiet way to accomplish this is to install "restricted software package" from your package manager. This package includes flash and many other of the most useful and common place apps you will need.

In ubuntu we have applications/add/remove...but I don't see anything about installing restricted software packages.  How to accomplish what you suggest?

Diesel79Commented:
Unless it has changed from older versions of of Ubuntu you should be able to install it straight from the add/remove.

See this site:
https://help.ubuntu.com/community/RestrictedFormats
(This is for older version but 9.04 should be the same as 8.10)

From the console you should be able to run:
sudo apt-get install ubuntu-restricted-extras
