Comment 2 for bug 595440

This bug report sucks a little, since the output of apt is in Italian. If anyone wants the error message in English, here you go:

As you can see, the script at /etc/kernel/header_postinst.d/nvidia-common fails.
The content of the script is:

########################################################################
#!/bin/bash -e
. /usr/share/debconf/confmodule
db_set nvidia-common/obsolete-driver false
db_input high nvidia-common/obsolete-driver || true

if [ -x /usr/bin/nvidia-detector ]; then
    LATEST=$(nvidia-detector)
    if [ ${LATEST} ] && [ "${LATEST}" != "none" ]; then
        db_fset nvidia-common/obsolete-driver seen false
        db_subst nvidia-common/obsolete-driver latest $LATEST
        db_input high nvidia-common/obsolete-driver || true
        db_go || true
    fi
fi

I'd greatly appreciate any help in order to fix this! I don't just want to add an exit 0 to the end of the script.
