Symantec Agent for Linux version

Note: The version (build number) reflects the version of the installer stub and typically matches the SEPM version but does not always match the agent version. This is because the installer stub is a script that downloads the latest version of the agent from the public repository, which may be more up to date than the SEPM version.
