如何卸载？

Answer 1

试着跑：

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

然后用以下内容删除包：

sudo apt-get purge fern-wifi-cracker

第一个命令将用一个永不失败的脚本替换预卸载脚本。

Answer 2

听起来这个程序有一个错误的卸载脚本。你可以试着清除它看看它是否有效。否则它需要一些真正的肘部油脂来摆脱。

sudo apt-get purge fern-wifi-cracker

希望这能有所帮助。

PS:也尝试重新启动，首先看到的是松了任何东西。
