Musescore 2.0 on other Ubuntu flavors

I have Lubuntu 14.04.2 installed, and I was told that Musescore 2.0 would work on various Ubuntu flavors, shuch as Lubuntu. I went to update my version of Musescore, but it didn't change anything. I uninstalled it, and downloaded and installed it. Still 1.3... I even tried resetting my computer. Still downloaded as 1.3...

Is it something wrong with the Ubuntu flavor, or just something that hasn't been covered yet?
