the postinst does:

if [ "x$1" = xconfigure ]; then
        if [ ! `getent group snmp >/dev/null` ]; then
                 deluser --quiet --system snmp
        fi
        adduser --quiet --system --group --no-create-home --home /var/lib/snmp snmp
        chown -R snmp:snmp /var/lib/snmp
fi

Which seems pretty weird.  What is this trying to do?

Cheers,
