Unable to install php-apc on Ubuntu 11.04

Question

I've got Ubuntu 11.04 running on my Slicehost web server, and I'm trying to install php-apc?

However, when trying to install with

apt-get install php-apc

I get:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package php-apc

Any idea how I gan get it installed?

Ubuntu Packages says is exists, but it's in universe. Have you enabled that repo?
