Erro na atualização de segurança Ubuntu

Após a notícia do blog sobre Vulnerabilidade afeta o Sudo no Ubuntu e derivado tentei fazer a atualização e deixar meu sistema seguro, mas obtive os seguintes erros:

Quais passos podem ser tomados pra resolver o problema?

O mirror br.archive.ubuntu.com está com pacotes misturados ou incompletos. Possivelmente porque estava no processo de espelhamento.

A princípio tentar novamente em algumas horas já resolve. Mas outra opção seria você trocar o servidor de download dos pacotes. A lista completa de espelhos achei aqui https://launchpad.net/ubuntu/+archivemirrors

Daí você faz a troca na mão mesmo (edita o /etc/apt/sources.list) ou no seu gerenciador de pacotes.

Ao tentar hoje mais cedo a atualização ocorreu sem problemas. Era o espelhamento mesmo!
