title: pysnmp convert (.my) to (.py) issue. Why always asks me to install the package?
body: <p>I am using Linux v.16</p>
  
  <p>I installed pysnmp package succesfully. I am trying to convert the <code>.my</code> to <code>.py</code> but I am facing errors:</p>
  
  <p><strong>1.</strong>
   using this command: <code>smidump -f python custom-mib.my | libsmi2pysnmp&gt;custom-mib.py</code></p>
  
  <p>The output was: </p>
  
  <pre><code>smidump: module 'custom-mib' contains errors, expect flawed output
  smidump: aborting due to severe parsing errors
  smidump: use the -k option to force continuation
  The program 'libsmi2pysnmp' is currently not installed.
              You can install it by typing: apt install python-pysnmp4
  </code></pre>
  
  <p>( the package is already installed. To make sure, when I apply the command: <code>apt install python-pysnmp4</code>, the result is "<code>python-pysnmp4 is already the newest version</code>"</p>
  
  <p><strong>2.</strong>
  When I use the command: <code>build-pysnmp-mib -o custom-mib.py custom-mib.my</code>,
  I am facing the same error saying to install the same package.</p>
