For 64-bit, download .tar.gz from the official site. click here and select “.tar.gz for other Linux”. Then do following steps.
1.) Extract the .tar.gz package and there only “libflashplayer.so” is what we need. Copy and paste this file to “/usr/lib/flash-plugin”. You can do this via the file browser (run sudo nautilus in terminal to launch file browser with root), or use following commands:
Open up a terminal (Ctrl+Alt+T) window, create “flash-plugin” folder:
sudo mkdir /usr/lib/flash-plugin/
go to the download page, and extract the .tar.gz: (replace the package name)
cd Downloads/ tar -zxvf install_flash_player_11_linux.x86_64.tar.gz
Navigate to extracted folder and do copy and paste:
cd install_flash_player_11_linux.x86_64/ sudo cp libflashplayer.so /usr/lib/flash-plugin/
2.) Change file permission via:
sudo chmod 775 /usr/lib/flash-plugin/libflashplayer.so
make a link for browser plugin:
cd /usr/lib/mozilla/plugins/ sudo ln -s /usr/lib/flash-plugin/libflashplayer.so . sudo chmod 775 libflashplayer.so
3.) Now, restart your Firefox or Chrome and flash should work.
