If you run an update on your DL, you'll see a new flashplayer package. This package is no longer dependent on a certain flashplayer version and as such, does not have the flashplayer version as the package version. This version is
1:0-4. Another update of this package is unlikely. While installing it, it will determine the latest flashplayer version (on the Ubuntu server!) and installs it. Further updates of the flashplayer will only be possible by reconfiguring the package using the update script:
sudo update-flashplugin
Or doing it manually:
sudo dpkg-reconfigure dbrs-flashplugin-installer
This means, you'll have to run the update occasionally yourself. It seems a bit complicated, but it's the only way without me keeping track on the current flashplayer version - which I won't!
