I'm trying to use Overtone but when I launch it, I get an error about jackd.

It is an almost fresh install of Ubuntu 14.04 where I installed leiningen and tried to install what is suggested here: https://github.com/overtone/overtone/wiki/Installing-and-starting-jack
The jackd command they suggest to run doesn't work either and gives errors too.
This is because your jack configurations are not set right with your audio card. Try downloading QJackCtl (a GUI for jackd) and start jack before lunching Overtone. If you successfully start jack with QJackCtl then overtone should start properly. In Ubuntu you should be able to find it with apt-get install qjack*
Note that you might want to choose playback only if you're not sure how to configure line-in (ex. microphone).
