Comment 1 for bug 551341

The following probably fixes the problem:

    sudo perl -i.bak -pe 's/SYSFS/ATTR/g' /lib/udev/rules.d/45-hpdjconsole.rules

But in my case, I don't have a "Hercules DJ Console", and realised this was installed as a dependency of djplay, which I don't use. So check if you actually need this. If not you can also just

    sudo aptitude purge libdjconsole0 libdjconsole-data
