I was uninstalling wine, and I saw that it also uninstalled LMMS at the same time. Thinking it was just something weird that happened, I went and tried lmms - naturally, it didn't start, saying it was uninstalled. So I tried sudo apt-get install lmms, and it listed wine1.4 as a package to be installed.

Why does LMMS need wine to run? It seems kind of counterintuitive/silly that Linux Multimedia Studio needs to be run as if it were made for Windows, not Linux.

Edit: My system is fully updated, and here's a picture of my terminal output when I try to install lmms. Note that all the other components, as listed by Uri, are installed completely:

I also tried sudo apt-get -f install, sudo apt-get clean and sudo apt-get autoclean, and none of those helped.
