Ubuntu server dpkg -l *couch* can't see packages in couchbase.list

With Ubuntu desktop (ubuntu-12.10-desktop-amd64.iso) I can download deb file package list and key:

sudo wget -O/etc/apt/sources.list.d/couchbase.list http://packages.couchbase.com/ubuntu/couchbase-ubuntu1204.list

wget -O- http://packages.couchbase.com/ubuntu/couchbase.key | sudo apt-key add

Then do ‘sudo apt-get update’ then 'dpkg -l couchbase and see

rc couchbase-server 2.2.0 Couchbase Server
un libcouchbase-dev (no description available)
un libcouchbase2 (no description available)
rc libcouchbase2-core 2.2.0-2453 library for the Couchbase protocol, core files
un libcouchbase2-libevent (no description available)

BUT! with Ubuntu server (ubuntu-12.10-server-amd64) the 'dpkg -l couchbase does not see packages.

What do I need to install?

Thanks

dpkg will only show packages that have already been installed at least once and are present in the local package cache (i.e. the package state). Use ‘apt-cache search’ or ‘aptitude search’ to search for uninstalled (specifically, never-installed) packages)

Thanks! That did the trick. I had installed and uninstalled, so the remnants were there. I am more familiar with Redhat systems at this point, so still have a lot to learn…
