Answer 1

Your syntax in code is wrong.

do this(from normal user, not root! also replace your_username with Your username :) ):

cp /usr/lib/flashplugin-installer/libflashplayer.so /home/your_username/.opera/plugins/libflashplayer.so

sudo apt-get install gecko-mediaplayer (not sure if it's nessesary but i'm just correcting syntax)

Answer 2

You can also try this, it assumes the file /usr/lib/flashplugin-installer/libflashplayer.so already exists.

In OPERA select:
Tools --> Preferences --> Advanced tab and then select Content from the list on the left.
Find the button named Plug-in Options... and click it.

In the Plug-in Options dialog you can add new paths like /usr/lib/flashplugin-installer and then enable it. (this info is kept in your $HOME/,opera/pluginpaths.ini file).

Now save the path changes and click the find new plugins. That should find it for you. You may need to restart Opera, but that should do it.
