Can't remove image due to error: "Error response from daemon: reference does not exist"
<p>I'm having a strange problem while trying to clear the images created by Docker. This is what I did:</p>

<ul>
<li><p>Remove all containers</p>

<pre><code>$ docker rm $(docker ps -a -q)
bb3927e956bf
3e2eeb6287c4
</code></pre></li>
<li><p>Check if there is any container running or created after:</p>

<pre><code>$ docker ps -a
CONTAINER ID    IMAGE    COMMAND    CREATED    STATUS    PORTS    NAMES
</code></pre></li>
<li><p>Remove all images: the first attempt failed because images were referenced</p>

<pre><code>$ docker rmi $(docker images -q)
Error response from daemon: conflict: unable to delete 2f21ea981017 (must be forced) - image is referenced in one or more repositories
Error response from daemon: conflict: unable to delete 2f21ea981017 (must be forced) - image is referenced in one or more repositories
</code></pre></li>
<li><p>Remove all images using <code>-f</code> option:</p>

<pre><code>$ docker rmi -f $(docker images -q)

Error response from daemon: No such image: 2f21ea981017:latest
Error response from daemon: reference does not exist
</code></pre></li>
</ul>

<p>Then this error: <code>No such image: 2f21ea981017:latest</code> comes up and I should ask, why? Where is such image? There is some kind of internal DB for Docker where it stores information?</p>

<p>After I run all the previous commands then I run the following and notice the output:</p>

<pre><code>$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
ubuntu              14.04.5             b1719e1db756        3 days ago          187.9 MB
</code></pre>

<p>But then I tried to remove the images again by running</p>

<pre><code>$ docker rmi b1719e1db756
Error response from daemon: reference does not exist
</code></pre>

<p>And I got the same error, what I am missing here? How I can fix this?</p>

<p>I should add that I've run also the commands from <a href="https://stackoverflow.com/questions/26127807/cannot-remove-docker-image-error-response-from-daemon">this post</a> but without success.</p>
