Appending the content of Bug #1190048 here, ignore me if its not useful
1. I expected there's a pre-installed GUI utility in Ubuntu to change hostname.
2. I expected it appears in GNOME Control Center(a.k.a. System Settings) ->
Details -> "Device name" textbox
* In fact there's really a "textbox" at the location but is not editable
and there's no "Unlock" button at that view.
3. I expected if I run GNOME Control Center as root (gksudo
gnome-control-center) I can change my hostname
* In fact when GNOME Control Center run as root, the "textbox" really
turn's into editable, but edit the content still won't apply to the system
temporarily nor permanently.
4. I supposed there's many user having the same conclusion like me, so please
help ;)

The "Device name" section under Details in the system settings on

be able to change the hostname of the system I was using.
