body: <p>When installing oracle-instantclient for ubuntu</p>
  
  <p><strong>What is the difference between installation with conda or ubuntu:</strong></p>
  
  <p>I am sure it is completely different. I just want to use some python scripts that access to an oracle server. 
  Options:</p>
  
  <ol>
  <li>Ubuntu install instructions for ubuntu</li>
  <li>Conda installation </li>
  </ol>
  
  <h3>1. Ubuntu install instructions</h3>
  
  <blockquote>
    <p>Installation</p>
    
    <p>See the Instant Client Home Page for more information about Instant
    Client packages.</p>
    
    <p>Client-server version interopability is detailed in Doc ID 207303.1.
    For example, Oracle Call Interface 12.2 can connect to Oracle Database
    11.2 or later. Some tools may have other restrictions.</p>
    
    <ol>
    <li><p>Download the appropriate Instant Client packages for your platform. All installations require the Basic or Basic Light package.</p></li>
    <li><p>Unzip the packages into a single directory such as C:\oracle\instantclient_12_2</p></li>
    <li><p>Add this directory to the PATH environment variable. If you have multiple versions of Oracle libraries installed, make sure the new
    directory occurs first in the path</p></li>
    <li><p>Download and install the correct Visual Studio Redistributable from Microsoft. Instant Client 12.2 requires the Visual Studio 2013
    redistributable. Instant Client 12.1 requires the Visual Studio 2010
    redistributable. Instant Client 11.2 requires the Visual Studio 2005
    redistributable.</p></li>
    <li><p>If you intend to co-locate optional Oracle configuration files such as tnsnames.ora, sqlnet.ora, ldap.ora, or oraaccess.xml with Instant
    Client, then create a subdirectory
    C:\oracle\instantclient_12_2\network\admin</p></li>
    </ol>
    
    <p>This is the default Oracle client configuration directory for
    applications linked with this Instant Client.</p>
    
    <p>Alternatively, Oracle client configuration files can be put in
    another, accessible directory. Then set the environment variable
    TNS_ADMIN to that directory name.</p>
    
    <ol start="6">
    <li>Start your application.
