Official Ubuntu PPA moved
you might not know me, but if you are using Monkey Studio on Debian, Ubuntu or some derivative distribution, I am the guy to blame if something does not work as it should ;)
For you as a user, this means that you have to change the URL to the PPA in your sources.list. I have updated the Linux Packages page, but for the impatient ones of you: just exchange every occurrence of http://ppa.launchpad.net/sargentd/monkeystudio/ubuntu with http://ppa.launchpad.net/monkeystudio/ppa/ubuntu and import the new key. Done, you are now using the official PPA and enjoy all the updates (and breaks) you expect!
Keep on hacking
