  1. List all the package versions available for 14.3RU8:

    seplpkg --platform all --product 14.3ru8 ls

  2. Create an unmanaged 14.3ru8 package for RHEL7 and RHEL8:

    seplpkg --platform "rhel7 rhel8" --product 14.3ru8 dl

  3. After downloading the LinuxInstaller stub from SEP Management server or Cloud Management server, create a fully installable package for Ubuntu 16, 18 and 20 (i.e. repackage):

    seplpkg --platform "ub16 ub18 ub20" --product RU8 --outdir /root/pkg rp LinuxInstallerStub

    • This command would download installers to the folder /root/pkg for all requsted Linux platforms. In addition, customer specific data from the STUB will be extracted and injected to each of the downloaded installer so the resulting installers in /root/pkg folder would enroll with respected management servers after installation.
  4. Create an unmanaged SEP 14.3ru8 client package for RHEL9:

    seplpkg --platform rhel9 --product 14.3ru8 download

    • Import the sylink.xml post installtion to enroll and be managed by the SEPM

      /opt/Symantec/sdcssagent/AMD/tools/sav manage -i sylink.xml

  5. Installing a downloaded package:

    seplpkg --platform "rhel7" --product RU8 --outdir /root/pkg repackage LinuxInstallerStub

    • The above command would download an installer for RedHat Enterprise Linux 7 to the folder /root/pkg with the file name "LinuxInstaller.rhel7.sep14.3ru8.<timestamp>". Copy this file to a system which has access to the Internet and run the installer. At the end of installation the installer would check with the Broadcom software repsitory on the Internet for software updates and if a newer version is available , it will download the latest version and update the product.


    • If the system is in an isolated environment without access to the Internet, run the installer with following option. This would install SEP Linux 14.3 RU8 without checking for software update.

      /root/pkg/LinuxInstaller.rhel7.sep14.3ru8.<timestamp> -- -g
