[Solved] How to activate autocompletion in terminal on RC3?

[belese]

Code:

echo "$BASH_VERSION"
4.2.37(1)-release

i'm on raspebrry, maybe it need a reboot when bash-completion was installed, to re-run init script.
i don't think i've reboot between test, if you want i can comment again, and redo test after reboot.

and to be sure we're talking same, auto-completion for file, executable was working, just apt-get auto-completion didn't work (and maybe other interactive).
