不建议在 Ubuntu 上安装 Backtrack 软件，因为它可能会混淆或破坏包管理器。但是，如果你想这样做，请打开终端并执行以下操作：
sudo bash
echo deb http://repo.offensive-security.com/dist/bt4 binary/ >> /etc/apt/sources.list
wget http://repo.offensive-security.com/dist/bt4/binary/public-key && sudo apt-key add public-key && sudo aptitude update
for i in $(cat backtrack.txt); do sudo apt-get -y install $i; done
现在，将以下内容复制到 Gedit 并将其保存到您的主目录中bt_menu_update.pl：

并在终端中运行：
cd ~/
mkdir menu_backup
sudo cp /usr/local/share/applications/* ~/menu_backup
然后perl ./bt_menu_update.pl。注销并重新登录，即可享受。
