Before installing the software, verify the software authenticity by validating the signature.

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 your public key to your RPM DB using this command.
    rpm --import <Public_Key_Name>

    If you don't import the public key using this command, you will get the following warning message during the installation.

    rpm -K McAfeeESP-<version_number>-<build_number>_x86_64.rpm
    rpm -K McAfeeRt-<version_number>-<build_number>_x86_64.rpm
    rpm -K McAfeeFW-<version_number>-<build_number>_x86_64.rpm
