在Ubuntu 16.04上安装metasploit

我正试图在Ubuntu 16.04上安装metasploit。我尝试使用命令安装依赖项

sudo apt-get install ruby libopenssl-ruby libyaml-ruby libdl-ruby libiconv-ruby libreadline-ruby irb ri rubygems

但是得到下面的错误

Building dependency tree       
Reading state information... Done
Note, selecting 'ruby' instead of 'irb'
Note, selecting 'ruby' instead of 'rubygems'
Package libopenssl-ruby 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 'libopenssl-ruby' has no installation candidate
E: Unable to locate package libyaml-ruby
E: Unable to locate package libdl-ruby
E: Unable to locate package libiconv-ruby
E: Unable to locate package libreadline-ruby 

我还尝试使用命令安装rvm

 \curl -L https://get.rvm.io | bash -s stable

但它也给出了以下错误

有人能提出解决方案吗？

我以前遇到过这个问题，我不得不添加一个ruby资源/存储库来从中下载ruby模块。您应该将kali linux存储库添加到资源文件中

darkoperator提供了其他示例来帮助您：

我忘了提到，ubuntu在vnware工作站中
