Comment 37 for bug 63450

Ricardo,

Your problem is unrelated to this bug. You appear to have a non-Ubuntu version of the update-rc.d program installed, which is normally provided by the sysv-rc package. In Ubuntu, versions 2.86.ds1-14.1ubuntu2 and above of sysv-rc support a "multiuser" option to update-rc.d; since your update-rc.d does not support this, you evidently aren't using the Ubuntu package.

You should correct this by installing the sysv-rc package from the Ubuntu archive in place of the non-Ubuntu one you currently have installed.
