Problemas com PPA

Olá pessoal, desculpe-me se estou postando no lugar errado, sou novo por aqui :v
Seguinte, todo tipo de aplicativo que tento instalar no terminal via PPA da erro quando vou dar apt-get update, dá erro 404 nos diretórios do ppa.
Já até formatei quando não sabia como remover esse ppa, mas agora sei.
A questão é que tenho que instalar algumas coisas, como, Google Drive e Jdownloader que são via PPA, mas sempre da o maldito erro.
Fico no aguardo, desde já muito obrigado e caso esteja postando no lugar errado, por favor me comuniquem ou movam esse post.

Onde estão os PPA's meu velho? Não vi nenhum na sources.list.

Mostre os tutoriais que vc tá tentando seguir...

-muitos PPA do 15.10 não funcionaram aqui
-talvez pelo pouco tempo de lançamento ainda não foram atualizados

Estão desinstalados os PPA por causa dos erros, mas o erro basicamente é esse 404 not found. vou tentar tirar um print.
