Hi.  
I have installed latest percona for 5.0.x version  
from [http://www.percona.com/downloads/Percona-Server-5.0/Percona-](http://www.percona.com/downloads/Percona-Server-5.0/Percona-) Server-5.0.91-22/deb/hardy/x86\_64/

But it seems xtradb is not there?

XtraDB isn’t in 5.0, it is based on the InnoDB plugin and is 5.1 and newer only. But a lot of our performance improvements were back-ported to the InnoDB in our 5.0 builds.
