You are right, nothing is obvious, especially in this context.

I will try to do what you say (I hope to find some help in some
documentation file).

It seems only shutdown command works. Nor scripts neither other commands
are executed.

With NUT version 2.6.3 (not autocompiled but from Ubuntu 12.04
repositories) instead all works fine. Therefore I think this problem is
not related to AppArmor or Selinux.
