Eu ainda sou novo no linux e atualmente uso o 14.04 e não tenho certeza do que fazer para resolver esta situação. O problema surgiu como eu estava apenas tentando instalar spotify seguinte este guia e encontrei-me recebendo as seguintes mensagens após o comando sudo apt-get update -qq

E: Some index files failed to download. They have been ignored, or old ones used instead.
E com certeza isso é repetido mesmo depois de digitar o sudo apt-get install spotify-client . Eu não os encontrei, então segui algumas diretrizes e tentei sudo apt-get upgrade seguido de sudo apt-get update mas não tive sucesso.
