Comment 13 for bug 1508110

Yes here is the process I followed when trying the PPA trunk version:

on the client: (ui packages were not installed)
sudo apt-get purge landscape-client landscape-common

sudo apt-add-repository ppa:landscape/trunk

sudo apt-get update

[ in landscape, deleted computer before next step ]

sudo apt-get install landscape-client landscape-common

sudo landscape-config
(enabled landscape, enabled scripts, set users to "ALL"), then registered with server at the end.
