Adobe Flash asks for update to watch youtube movies

What is the full Terminal output of the following command?

lsb_release -a; uname -a; dpkg -l | egrep 'flash|gnash|swf|spark|restricted'

Dear Mark, I have no idea where and how I have to find what you ask for. Ubuntu is runting for years on my harddesk PC but I am not a specialist at all. I can check the Ubunt software center which says to me that I have flashplugin-installer 11.2.202.310ubuntu0.12.04.1 properly installed and till a week ago I could watch youtube movies without problem but now I get the error code that I need an update of adobe flash. I downloaded it but I have no idea how to install it. I am not famliar at all with Ubuntu software ... any suggestions?

If you are using the Gnome interface, open the Terminal console via "Applications->Accessories->Terminal"

If you are using the Unity interface (default graphical user interface in Ubuntu), use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that.

So the methods in Unity are:

Press CTRL-ALT-T key combination.

Dash > Search for Terminal

Dash > More Apps > 'See More Results' > Terminal

Dash > More Apps > Accessories > Terminal

If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the following diagnostic command:

lsb_release -a; uname -a; dpkg -l | egrep 'flash|gnash|swf|spark|restricted'

Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

Then copy-paste the output of that command into the following thread:

I am NOT asking you to be an Ubuntu expert, but to simply copy-paste a Terminal command and send the output.....

Sorry Mark, appreciating your help a lot.
This is the output:

Does this help? What do I have to do next?

Copy-paste these Terminal commands one by one into the Terminal:

cd $HOME
rm *.deb
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo dpkg -i google-chrome*.deb
# fix the Google Chrome dependencies issue
sudo DEBIAN_FRONTEND=noninteractive apt-get --yes --force-yes -f install

Then run Google Chrome which contains the newest version of Adobe Flash plugin.

Dear Mark,

Any idea how we can solve this in Firefox as we are using this browser in stead of google chrome...
Thanks!
Eddy

In google-chrome we had no problems in opening youtube movies - or should we just all the time use google chrome instead of Firefox?

See http://www.adobe.com/software/flash/about/

Adobe does not provide a flash player higher than 11.2.202 for Linux with Firefox. If you need a highe version, then the only chance you have is using chrome.
