I wanted to change my desktop environment (DE) to cinnamon because it was way faster on my test computer.
I ran the command:
apt-get install cinnamon-desktop-environment
Changed the DE to Cinnamon.
Put my password in, and then it kicked me back into the greeter.
When I looked at the logs, I found this error message:
Mar 5 13:28:39 lab-linux-01 cinnamon-session: GLib-GIO-ERROR: t+0.01202s: Settings schema 'org.gnome.desktop.file-sharing' does not contain a key named 'enabled'#012aborting...

Googling around for this error message did not yield very much help.
