What is a clean way to install Flash on ubuntu server 12.10? The package flashplugin-installer doesn't seem to be available any more. Is it no longer packaged? Or would I need to do something like step 3 in http://askubuntu.com/questions/11/how-do-i-install-adobe-flash-player even though that seems to be for Ubuntu Desktop edition, not Ubuntu Server.
This is for incorporation with Firefox for testing.
