Estou recebendo esse erro sempre que tento executar qualquer comando apt-get. Atualmente estou tentando executar o sudo apt-get update. Também notei que está /var/lib/apt/listsvazio.
Como posso preencher novamente este diretório com os arquivos necessários que mostram os aplicativos instalados? Existe um CD de reparo de inicialização que eu possa usar ou algo para corrigir isso?
Recebo o seguinte erro quando tento executar apt-get update,
sudo apt-get update

Estou usando Ubuntu 13.10
Depois de executar o comando que @muru postou abaixo, esta é a saída:
$ sudo strace apt-get update

Também deve ser observado que se você receber um E: Sub-process returned an error codeerro ao executar algo parecido apt-get remove [pkg]ou obter erros ao executar, apt-get updatevocê pode querer ter certeza de que seu /tmpdiretório não foi excluído.
A recriação do /tmpdiretório corrigiu meu erro, pois nenhum aplicativo poderia utilizar um diretório temporário para armazenar arquivos temporários. Conforme referenciado pela última resposta aqui http://ubuntuforums.org/showthread.php?t=1677090.
Eu fiz esta resposta para completar.

É possível que você tenha uma instalação incompleta? Se for esse o caso, você pode corrigi-lo usando sudo apt-get install -f. Isso pode resolver seu problema.
Se isso não resolver o erro quando você executar sudo apt-get updatenovamente, tente executar
sudo dpkg --configure -a
sudo apt-get install -f
No passado, se dpkg fosse o subprocesso que estava apresentando o erro, ele normalmente apareceria na mensagem de erro, mas talvez ainda seja a fonte dos seus problemas.

Eu /tmpjá existia, mas havia arquivos/diretórios desnecessários que removi:
rm -rf /tmp/*
Executado sudo apt updatee funcionou normalmente.

Eu uso esses dois comandos e funciona bem.
sudo apt-get remove libappstream3
sudo apt remove libappstream3
