通过 安装软件时dpkg -i packageA.deb，是否会packageA自动下载并安装所需的依赖项？这与使用apt-get或 有aptitude什么不同？
上面的错误是什么意思？什么是安装候选？
我试图做
sudo apt-get install munin-memcached
我收到这条消息：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package munin-memcached is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package munin-memcached has no installation candidate
我用谷歌搜索了这个问题，有人说要做一个，apt-get upgrade但它仍然没有解决我的问题。
我想知道是否有任何方法可以在 Ubuntu 12.04 上安装sqlmap, nikto, john, aircrack-ng, ... 等Kali 工具？
如果是，那么我应该如何进行？
