Eu tive que percorrer um longo caminho para pegar o Steam, já que estava recebendo o Error 403 Forbidden. Eu trabalhei em torno disso, mas quando o Steam é iniciado, sou informado de que deseja adicionar arquivos adicionais. Quando clico no aplicativo, recebo uma mensagem sugerindo que eu instale esses arquivos. Quando corro, recebo o seguinte diálogo no console:
>Steam needs to install these additional packages:
> libgl1-mesa-dri:i386, libgl1-mesa-glx:i386, libc6:i386

Por favor, alguém pode aconselhar? Estou executando um G5 PowerMac, rodando o ubintu-MATE 16.04. Alguma idéia de como fazer isso funcionar?
