DataStax OpCenter Fails to Install
<p>I'm trying to install DataStax OpsCenter onto a fresh Debian 8.2 install and it's erring during installation with the following:</p>

<pre><code>Setting up opscenter (5.2.2) ...
Generating a 1024 bit RSA private key
....................................++++++
......................++++++
writing new private key to '/var/lib/opscenter/ssl/opscenter.key'
-----
keytool error: java.lang.IllegalArgumentException: java.io.IOException: Invalid char:  
dpkg: error processing package opscenter (--configure):
 subprocess installed post-installation script returned error exit status 1
Processing triggers for systemd (215-17+deb8u3) ...
Errors were encountered while processing:
 opscenter
E: Sub-process /usr/bin/dpkg returned an error code (1)
</code></pre>

<p>Oracle's Java 8 (JVM only) is already installed and verified as you can see here:</p>

<pre><code>java -version
java version "1.8.0_74"
Java(TM) SE Runtime Environment (build 1.8.0_74-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.74-b02, mixed mode)
</code></pre>

<p>It seems to be failing during creation of an RSA key, presumably for the SSL site. </p>

<p>I'm installing this using the DataStax APT repo. Any idea how to fix this? I've tried installing from 5.2.4, 5.2.3 and 5.2.2. </p>
