Reinstall flashplugin under Ubuntu

Sometimes it happens that the flashplugin update under Ubuntu not properly working. The best way for me is, to reinstall the .deb package again.

Download the .deb package

sudo apt-get download flashplugin-installer

Install the .deb package

sudo dpkg --install /var/cache/apt/archives/flashplugin-installer_*VERSION*.deb

Replace VERSION with the available version of the installer.
Thats it. :-)
