Problemas na atualização 6.10 > 7!

[sparcx86]

Oi pessoal, estou com problemas ao tentar atualizar meu ubuntu 6.10 edgy para o 7.
Nâo tenho cd do 7, quero atualizar pela internet mesmo pois ao ver os tutoriais me pareceu fácil, mas no meu caso não tá tão facil assim!
Segui exatamente como diz este tutorial:
http://www.howtogeek.com/howto/ubuntu/upgrade-ubuntu-edgy-to-feisty/

Porém, não consegui completar o upgrade, ele sempre dá pau...

Abaixo meu sources.list (é o original, ainda assim muitas urls dão erro pois não estão mais ativas.)

Peço se possivel alguem me enviar um sources.list que funcione e eu possa atualizar meu sistema, já que meus problemas principalmente com o kde que não roda nesta versão serão solucionados....
