Você pode instalar o openjdk7 na Ubuntu Store, clicar com o botão direito do mouse em "Minecraft" e clicar em executar com o OpenJDK7.
Primeiro, tentei baixar o Minecraft. Eu entrei e o lançador funcionou. Mas, quando tentei "jogar Demo", foi isso que apareceu:

Eu também quero saber como instalar arquivos tar.gz. O Google não me oferece ajuda. É assim que eu quero instalar o OpenJDK7 x64. (ou seja, no site da Oracle).
Eu tenho o Ubuntu 12.10 LTS. O servidor funciona bem e todos os seus recursos. É apenas o jogo que me preocupa.
