body: <p>Having trouble getting Oracle XE 18c installed on OpenSuse Leap 15.0... When running the configuration script:</p>
  
  <pre><code>joshua@linux-t1zu:~&gt; sudo /etc/init.d/oracle-xe-18c configure

  <p>I see where it first says something along the lines of</p>
  
  <p>Host name or host name resolution is misconfigured.
  linux-t1zu: linux-t1zu: Name or service not known</p>
  
  <p>So does this mean I need to configure localhost? If it is already not?
  I'm honestly pretty much lost here. Any advice is greatly appreciated.</p>
