Issue/Introduction

When attempting to install the Linux agent for Symantec Endpoint Protection (SEP) or Symantec Endpoint Security (SES), the installation fails with "Error 1: Agent installation failed."  Reviewing the sdcss_install.log shows the following error:

03/22/23 21:04:05: installDependency: Missing dependent at on rhel(*)
03/22/23 21:04:05: installDependency: install (at)

No package at available.
Error: Nothing to do
03/22/23 21:04:05: installDependency: Dependent package at not installed on rhel7

* refers to rhel7 or rhel8 ...etc

Environment

Red Hat Enterprise Linux (RHEL)

Cause

This error occurs because one or more dependent packages is missing from the system and the installer could not automatically install them from the currently configured repositories.  

Resolution

Install the missing dependent packages. For example:

sudo yum install at

For RHEL environments, the following packages are required by the installer: 

• at
• audit
• elfutils-libelf
• zip
• checkpolicy
• policycoreutils-python
  
  

For a full list of dependent packages, see the Dependencies section of System Requirements documentation.
