Problemas no ubuntu 12.04

[eduxeu]

E:Malformed line 59 in source list /etc/apt/sources.list (dist parse)

Não consigo abrir a central de programas. Sempre recebo a mensagem acima em vermelho.
Algume pode me ajudar. Não consigo ouvir musicas nem visualizar vídeos.

Obs: Este problema começou logo que eu fiz uma atualização.
Sou Iniciante ao extremo com linux.

Obrigado pela atenção!
