I installed Ubuntu 14.04 beta 2. After problems with the ttf-mscore-installer I managed to, in the process of trying to fix it, lose sound and all admin privileges so that I couldn’t even mount a usb to save anything.
I am now on my second fresh install. This is why I suggest people wait to install Ubuntu 14.04 until it is officially released on April 17. It has been a while since I have installed a beta, but I knew what I was getting into. You have to expect problems, that’s why it is called a beta.
