Installation of metasploit on Ubuntu 16.04
<p>I am trying to install metasploit on Ubuntu 16.04. I tried installing the dependencies using command </p>

<pre><code>sudo apt-get install ruby libopenssl-ruby libyaml-ruby libdl-ruby libiconv-ruby libreadline-ruby irb ri rubygems
</code></pre>

<p>but getting the error below</p>

<pre><code>Building dependency tree

Note, selecting 'ruby' instead of 'irb'

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

</code></pre>

<p>i also tried installing rvm using command</p>

<pre><code> \curl -L https://get.rvm.io | bash -s stable
</code></pre>

<p>but it also give following error</p>

<pre><code>% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
