Apple wireless mouse and keyboard does not work

I paired the mouse and keyboard on Ubuntu, but it seems not work.

I got this error in /var/log/syslog:

Nothing appears in xinput --list, only the wired mouse and keyboard. How to fix that?

This is a known bug, and has been for about 2 years now, unfortunately:
