my hardy system cannot play you tube videos and spits a message saying adobe flash player is not installed.when i try to install it,terminal says it is already installed.but synaptic shows it not installed.what should i do?

Terminals don't really say anything. What command did you enter in the terminal to find out if the flash plugin was installed or not? and what was the exact response? What browser are you running? Can you post the results of here. The first one or two letters on the response are all-important. Also can you give the locations of the file libflashplayer.so on your system.

i am getting this result...
but i cannot able to view any videos...

Just go to adobe.com and download the flash plugin. Get the .tar.gz file and not the .deb package. Extract it and copy libflashplayer.so to /usr/lib/mozilla/plugins (don't even run the installer that comes with the package - just copy the file manually).

I agree with you Udi. That's how I do it. The point is the OP obviously had not installed the package. I am curious how, exactly, the terminal told him it was installed.


Rajavel or Raphtor: what the aptitude output tells us is that the flashplugin package is not installed. What did the terminal tell you that made you believe a plugin was installed?

Raphtor,
To learn more of Linux workings, proceed as you have so far.
To make it work quickly take another course, enable the Universe or Multiverse repositories, install linux-restricted-modules or install flashplugin-nonfree. Either way the flashplugin-nonfree installs, connects to Adobe, downloads & installs flash so that it works.

There is also a non proprietary flash player for Linux.

Eric, I think Raphtor must have those repos in his sources.list or aptitude would not have returned the message it did. He didn't install the package, though.

#abhinav@raphtor:~$ aptitude search flashplugin-nonfree
i flashplugin-nonfree - Adobe Flash Player plugin installer

packages HAVE to be installed as root
try sudo apt-get install flashplugin-nonfree

of course i used root.this is the output for
#aptitude search flashplugin-non free.

i flashplugin-nonfree - Adobe Flash Player plugin installer



the "i" indicates it is already installed.isnt it?

yes, it does

ok assuming it is an installation problem, how can i uninstall it and reinstall?the synaptic shows it as not installed.....

cheers,
jdk

Also note this too-I have hardy and when I try to play Pureplay Poker it wouldn't run and I had both Adobe flashplayer and flashplayer-nonfree plugin. After I uninstalled Adobe Flash Player, but kept flashplugin-nonfree, everything worked fine.
Hope that helps some...

Raphtor,
Having flashplugin-nonfree installed is not same as flashplugin-nonfree having installed flash player. Did you run flashplugin-nonfree? When it ran, did it prepare your system, download flash player from Adobe, then install it?

Never has command line install of Adobe flash player resulted in videos playing in my computers. Install yes, play no.
Using a graphical installer to install flashplugin-nonfree has always made videos play.
You seem to want to learn how it works, that is good, very good. I am often satisfied to just see it work, so I use flashplugin-nonfree and watch videos. If you chase this to find all the problems, please post details.
