[ubuntu] Compiz Animation Add-On's Missing on Ubuntu 12.10 64 Bit

view story

http://ubuntuforums.org – Hi, I am new to this forum, and I have a small problem with compiz, and its settings manager. For some reason, I can't seem to get the Animation Add-On to appear in the settings manager. (I am really desperate for the burn effect!!!) When I install compiz-plugins-extra from Synaptic, nothing happens. And I can't seem to at all install compiz-fusion-plugins-extra which is what I have been also trying to do as well. When I type "sudo apt-get install compiz-fusion-plugins-extra" in the terminal, Terminal tells me "E: Unable to locate package compiz-fusion-plugins-extra" (Hardware)
