Eu tenho exatamente o mesmo problema do Atualizador de Software - Nenhuma atualização automática Atualizador de Software - Sem Atualizações Automáticas .
Breve histórico: Quando houve um problema com o atualizador automático de software, (não consigo instalar algum pacote), li no fórum e resolvi o problema: instale o gerenciador de pacotes Synaptic e fiz atualizações manualmente. Atualizações automáticas eu desligo. Depois de algum tempo eu percebo quais atualizações de software do Ubuntu funcionam corretamente, então eu mudo as atualizações automáticas. Mas nenhuma atualização automática é iniciada.Screenshot do Software & Atualizações
