The simplest way to install the flash player on Debian GNU/Linux is to install the flashplugin-nonfree package from the contrib external repository.

Make sure the contrib repository is enabled in /etc/apt/sources.list or /etc/apt/sources.list.d/, and then do:

sudo apt-get install flashplugin-nonfree

If you want to check for flashplayer updates, do:

sudo update-flashplugin-nonfree --install

Note that this is proprietary software, and is not part of Debian itself.
