# Verify the signature on Ubuntu systems

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

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.

`gpg --import &lt;Public Key&gt;`
4. Verify the signature.

`dpkg-sig -verify McAfeeESP-&lt;version_number&gt;-&lt;build_number&gt;.deb`

`dpkg-sig -verify McAfeeRt-&lt;version_number&gt;.&lt;build_number&gt;.deb`

`dpkg-sig -verify McAfeeTP-&lt;version_number&gt;.&lt;build_number&gt;.deb`

`dpkg-sig -verify McAfeeESPFileAccess-&lt;version_number&gt;-&lt;build_number&gt;.deb`

`dpkg-sig -verify McAfeeESPAac-&lt;version_number-&lt;build-number&gt;.deb`

You get a message similar to `Processing McAfeeTP-&lt;version_number&gt;-&lt;build_number&gt;.deb... GOODSIG _gpgbuilder 284E8BE753AE45DFF8D82748DDDF2F4CE732A79A 1414371553`
