atualização de pacotes

[sousac]

ola pessoal, estou com o ubuntu 10.10, e não consigo atualizar os pacotes, quando tento atualizar pelo gerenciador de atualizações apresenta erro do tipo "nen todas atualizações podem ser instaladas, o índice de software está danificado", e pede que eu execute "sudo apt-get install -f" em um terminal para resolver esse problema primeiro, só que quando executo pelo terminal apresenta o erro "E: O dpkg foi interrompido, para corrigir o problema tem de correr manualmente 'sudo dpkg --configure -a' , quando executo no terminal o "sudo dpkg --configure -a" aparece a mensagem abaixo e não conclui.

Colega, repita o procedimento para ver se resolve, pelo que entendi essa fonte do flashplayer deveria ser retirada e/ou acertada.
Tente entrar no Ubuntu no modo de recuperação, existe a opção de consertar pacotes problemáticos.

Valeu  loca100, segui os procedimentos sugeridos, após reiniciar no modo normal executei um apt-get update e depois fui ao gerenciador de atualizações atualizou tudo sem problemas.

obrigado pela dica,
