Uninstaling Geonode

I have an installation of Geonode R 2.01 running under Ubuntu 12.04. I tried to uninstall it using the following commands:

sudo apt-get remove --purge geonode
sudo apt-get autoremove --purge
sudo rm –r /etc/geonode

Then I tried to reinstall it using the following commands:

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:geonode/release
sudo apt-get update
sudo apt-get install geonode
geonode createsuperuser
sudo geonode-updateip 127.0.0.1

In the latest command I had the error that I uploaded in the file so I assume that there is a file or subdirectory that I didn't delete it. I tried to look at it but without success. Does any one have an idea of the file or sub directory that I missed it.

Additional to remove Apache, I had to uninstall the layers installed in Geoserver. In my version are located in /var/lib/geoserver/geonode-data/, then reinstall the whole thing and should work.
