Thread:Talk:RPi raspi-config/Change keyboard doesn't work

I an using Jessie Lite on my Pi. I've been configuring it with raspi-config. When I select Change Keyboard Layout in order to set the compose key, I get kicked out and back to the terminal screen with the error...

update-rc.d: warning: start and stop actions are no longer supported; falling back to defaults ''Reloading keymap. This may take a short while''

What can I do to set up the compose key?
