如何卸载？
答案1
尝试运行：
echo -e '#!/bin/bash\nexit0' | sudo tee /var/lib/dpkg/info/fern-wifi-cracker.prerm
然后使用以下命令删除该包：
sudo apt-get purge fern-wifi-cracker
第一个命令将用永不失败的脚本替换预卸载脚本。
答案2
听起来这个程序的卸载脚本有问题。你可以尝试清除它，看看是否有效。否则，你需要付出很大努力才能清除它。
sudo apt-get purge fern-wifi-cracker
希望这可以帮助。
附言：另外，请先尝试重新启动，看看是否可以放松任何限制。
