alguém sabe o que pode ser?

valeu!

Cara, o apt-get não deve ser usado diretamente (invocado por comandos seus).

Eu recomendo utilizar somente o aptitude.

Com os dois instalados, se você instalar pacotes pelos dois utilitários, há chances de corromper o sistema.

Tenta re-instalar o aptitude.

Abraço!
