tentando instalar o foobnix usando terminal sem sucesso

então, de acordo com as instruções dos arquivos leia-me e do foobnix wabpage, preciso digitar esses comandos no terminal para instalar o foobnix

sudo add-apt-repository ppa:foobnix-team/foobnix-player
sudo apt-get update
sudo apt-get install foobnix

e eu estava fazendo exatamente isso e foi isso que aconteceu:

sudo add-apt-repository ppa:foobnix-team/foobnix-player

resultados da atualização, não li a versão por muito tempo

a lot of stuff linked to foobnix hasn't been downloaded from launchpad because of 404 error 
E: Some index files failed to download. They have been ignored, or old ones used instead.

e finalmente

sudo apt-get install foobnix
