# Verify the signature on Ubuntu systems

Update the GPG in the Ubuntu database, and verify the authenticity of the software.

 
 

## Task

1. Log on to the system as a user with administrator rights.
2. Locate the public key (GPG) from the software download site.
3. Import the public key. 
  
 <kbd>gpg --import &lt;Public Key&gt;</kbd>
4. Verify the signature. 
  
 <kbd> dpkg-sig -verify McAfeeESP-&lt;version_number&gt;-&lt;build_number&gt;.deb</kbd> 
  
 <kbd>dpkg-sig -verify McAfeeRt-&lt;version_number&gt;.&lt;build_number&gt;.deb</kbd> 
  
 <kbd> dpkg-sig -verify McAfeeFW-&lt;version_number-&lt;build-number&gt;.deb</kbd> 
  
 You get a message similar to 
 <kbd>Processing McAfeeFW-&lt;version_number&gt;-&lt;build_number&gt;.deb... GOODSIG _gpgbuilder 284E8BE753AE45DFF8D82748DDDF2F4CE732A79A 1414371553</kbd>
