"listen" conflict when installing Jekyll with Docker
<p>I am trying to install Jekyll in a <code>Dockerfile</code> extending the Jenkins official image (2.19.1)</p>

<p>The following commands :</p>

<pre><code>RUN apt-get install -y ruby-full rubygems
RUN gem install jekyll
</code></pre>

<p>produce the following error :</p>

<pre><code>Step 2 : RUN gem install jekyll
