Minecraft

Oftentimes installing Mminecraft seems to be hard for end-users to figure out in XUbuntu 12.04. There is a PPA for this that will make the installation quite simple with just a few commands in the terminal. Since this is a quick fix, Tech Support volunteers can do this as a walk-in in less than ten minutes time.

  sudo add-apt-repository ppa:minecraft-installer-peeps/minecraft-installer
  sudo apt-get update
  sudo apt-get install minecraft-installer
