Ubuntu Flash Problem " adobe-flash plugin is virtual."

I recently installed Ubuntu. It is so called another version of linux. It is self-claimed as the safest and most stable engine.

I am a beginner for this OS. The first thing I got stuck is installation of Flash. I tried to install flash from Adobe. http://get.adobe.com/flashplayer/
However, I got this error - " adobe-flash plugin is virtual."  The program to solve it is at the bottom of this page.

I looked around in the internet. One of the guy said that I installed Ubuntu 64 bit Version. This is very common ( I guess). This bug is listed with links to a few solutions https://bugs.launchpad.net/ubuntu/+s...rl/+bug/554449

If you are facing the same problem as me, you can check out whether you have installed 64 bit version.

1.Checking 64 bit OS?
Applications -> Accessories->Terminal

Type uname -a

If the the last few words as "Linux ubuntu 2.6.32-26-generic #48-Ubuntu SMP Wed Nov 24 10:14:11 UTC 2010 x86_64 GNU/Linux"

This shows that you could use the following solutions.

2. Installaion

There are many ways as what I said. You could try install it through the update manager. Or you could directly download a program from a blog which is made by LovingLinux.

It works for me.

Good luck.
