lsb_release: command not found in latest Ubuntu Docker container : <p>I just wanted to test something out real quick. So I ran a docker container and I wanted to check which version I was running:</p>

<pre><code>$ docker run -it ubuntu    
root@471bdb08b11a:/# lsb_release -a
bash: lsb_release: command not found
root@471bdb08b11a:/# 
</code></pre>

<p>So I tried installing it (as <a href="http://www.andryhacks.com/bash-lsb_release-command-not-found/" rel="noreferrer">suggested here</a>):</p>

<pre><code>root@471bdb08b11a:/# apt install lsb_release
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package lsb_release
root@471bdb08b11a:/# 
</code></pre>

<p>Anybody any idea why this isn't working?</p>
