Environment

Red Hat Enterprise Linux (RHEL) and Ubuntu

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:

For RHEL # sudo yum install at

For Ubuntu # sudo apt install at

The following packages are required by the installer: 

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