O que devo fazer para corrigir o erro?

[Luciano Gardim]

Pelo que me parece você abriu outro programa como Synaptic, apt-get, aptitude
ou o atualizador, e assim o "aptitude update" não pode obter a trava.

Feche o outro programa que esta travando e tente rodar o update de novo.

[cadubts]

Obrigado Luciano.

Você tem razão. Fechei o console abri somente o Synaptic e ao recarregar deu certo.

[Luciano Gardim]

Jóia.

Lembrando que  não podemos rodar 2 programas de atualização ao mesmo tempo.

Qualquer dúvida, estou à disposição.

Abraços.
