I'm sorry, but this solution sucks. It doesn't even work. Ever heard of QA? Took me almost an hour to diagnose it. I could have just developed it myself in the same amount of time. Long story short, put --user 0:0 in advanced parameters so you don't get the permission issues due to using the incorrect user. If you don't already have this installed, I'd look for a better solution as even this is technically not a proper fix and I don't care to put any more time into this.
