If you want to play youtube and some other flash files, flash plugin is a must for your browser. To install Flash plugin for Mozilla Firefox is not difficult at all, usually the browser will prompt out a wizard and guide you through the installation process. But for the latest version of Ubuntu(gusty 7.10), there’s a known bug affecting the Flash plugin in the Gutsy repo. User will get the error saying that the flash plugin is not installed even though the user has already installed the plugin.

To solve this problem:

Solution 1

Download the following debian package and install it manually

- Download debian package

wget http://mirror.ne.gov/ubuntu/pool/multiverse/f/flashplugin-nonfree/

flashplugin-nonfree_9.0.115.0ubuntu3_i386.deb

- Install the downloaded package, either double click to install it or open a terminal and type the following command

dpkig -i flashplugin-nonfree_9.0.115.0ubuntu3_i386.deb

Solution 2

- Download the source file from adobe website

wget http://fpdownload.macromedia.com/get/flashplayer/current/

install_flash_player_9_linux.tar.gz

- Untar and install

tar zxvf install_flash_player_9_linux.tar.gz

cd install_flash_player_9_linux

sudo ./flashplayer-installer

- A few questions will be ask during the installation, when the installer ask for the installation path, please put the following path

/usr/lib/firefox

Note:

if user didn’t use sudo to execute the installer, eg:

./flashplayer-installer

user won’t be able to change the installation path, so make sure execute the installer with sudo
