Ubuntu Maverick (beta) repository problem

I used to be a Fedora distro fan, but considering the popularity of Ubuntu, I have decided to try Ubuntu, and downloaded the latest one, Ubuntu Maverick (10.10 beta) .

After installation, first I enabled Ubuntu Multiverse repository then tried to install vlc applying the following command in terminal:

sudo apt-get update

sudo apt-get install vlc vlc-plugin-pulse mozilla-plugin-vlc

But I got this error:

Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Couldn’t find package vlc
