Since you're on Ubuntu, there's a fairly easy way.
* Install all the 9.1 stuff - server, client, etc.
* Run pg_upgradecluster
* Verify it's all working OK on the new DB.
* Uninstall the 9.0 stuff
Note that the 9.1 server will get installed on a higher port number so
it doesn't conflict with the existing server package.. You'll want to
edit postgresql.conf and change it back to normal once you're done.
