Missing Reverb

Since 2 weeks I am using Xubuntu and downloaded Audacity 2.0.3.
In the effects menu there are a lot of effects, but there is no reverb. Am i looking at the wrong place, or is there something else wrong?
Who can give me a clue?

A new reverb effect was introduced in Audacity 2.0.4 so should soon be available in the Ubuntu repositories (but not yet).

There is a good reverb effect in the “Calf” plug-in pack, which should be available in the repository (“calf-plugins”). When installed, restart Audacity and the Calf plug-ins should be listed below the divider in the Effect menu.

Thanks for the tip Steve. Similar situation with Debian - old audacity in the stablle release still, but I easily installed the calf plugins, at first listen reverb is good.
