Flash video not functioning

Applications>accessories>terminal and type

sudo apt-get install flashplugin-installer

or you can edit source list with

gksudo gedit /etc/apt/sources.list

and look for line

deb http://archive.canonical.com/ubuntu hardy partner

If you don't have it add it.If it is # sign in front of the line remove it so the lie will look like above.Save and close file.

sudo apt-get update

In synaptic search for adobe-flashplugin and install it.

All the above steps are already completed. The step I had not done earlier was deleting the # sign. But still after that, the browser says "Hello, you either have JavaScript turned off or an old version of Adobe's Flash Player. Get the latest Flash player."
Please help.....

After removing # sign in sources list did you update it with

sudo apt-get update && sudo apt-get upgrade

After that you should be able to find adobe-flashplugin in synaptic and install it.

Just in case you can also check that you have JavaScript enabled in Firefox under preferences>content.

completed sudo apt-get update & sudo apt-get upgrade.
Javascript is also enabled. Also checked flash plugin, named as flashplugin-nonfree in synaptic. It is installed.
But still the same message.

In synaptic find adobe-flushplugin and install it.Remove flashplugin-nonfree.

Are you sure adobe flash player and flashplugin-nonfree are not the same.
I referred the question "Flash video does not function properly in Firefox (3.07) using Ubuntu 8.10"
I tried searching for adobe-flushplugin and adobe-flashplugin both. But none of them seem to exist in synaptic.

This can be source of mistake,It is my overlook.You use Intrepid so line should look

deb http://archive.canonical.com/ubuntu intrepid partner

Change that in your source list and after that refresh source list with

sudo apt-get update

Now you should find adobe-flashplugin in synaptic.
