[Resolvido]Gerenciador de Atualizações -Não foi possível inicializar pacote

[Rondiny]

Pessoal, sou novo usuário do Ubuntu 11.04. Tenho um problema. o meu gerenciador de atualizações ao ser aberto aparece a mensagem:
"Não foi possível inicializar as informações do pacote"

"Um problema impossível de resolver ocorreu erro enquanto inicializava as informações  do pacote."

"Por favor relate este erro do pacote 'update-manager' e inclua a seguinte mensagem de erro:"

" 'E:Tipo 'exit' não é conhecido na linha 61 na lista de fonte/etc/apt/sources.list'  "

O que devo fazer?

Obrigado,
Rondiny
