Hi and welcome,

I dont know or use EMC2, but here:
LinuxCNC.org - Download information
it says

Note: Do Not upgrade Ubuntu from 6.06 to 8.04 or upgrade from 8.04 to 8.10. The precompiled versions of EMC2 are only compatible with the Ubuntu version they were compiled with. Upgrading will remove the EMC packages and make your system unable to run EMC.

What version of ubuntu are you running?

There is documentation on how to get it running with a current 9.10 ubuntu:
EMC Documentation Wiki: EMC Ubuntu91

It involves compiling from source.
And while this is certainly possible, packaging the files after compiling might be desireable.
If that would prove to be difficult, I would rather prefer a ubuntu 8.04 + emc2 packages for a production environment
