como desinstalar?

    

Answer 1

Tente executar:

echo -e '#!/bin/bash\nexit0' | sudo tee /var/lib/dpkg/info/fern-wifi-cracker.prerm

e, em seguida, remova o pacote com:

sudo apt-get purge fern-wifi-cracker

O primeiro comando substituirá o script de pré-desinstalação por um script que nunca falha.

    

Answer 2

Parece que o programa tem um script de desinstalação incorreto. Você pode tentar limpá-lo para ver se isso funciona. Caso contrário, vai precisar de alguma graxa de cotovelo para se livrar.

sudo apt-get purge fern-wifi-cracker

Espero que isso ajude.

PS: tente também Rebooting primeiro para ver o que solta qualquer coisa.
