EDR: Fail to install Server on EL 8.x with redis error

Products

• Carbon Black EDR (formerly Cb Response)

Issue/Introduction

• yum install cb-enterprise fails with error

Problem: package cb-enterprise-7.2.0.200713.0019-1.el8.x86_64 requires redis = 5.0.9, but none of the providers can be installed
- conflicting requests
- package redis-5.0.9-1.el8.remi.x86_64 is excluded"

 

Environment

• EDR Server: 7.1 or higher
• Linux: 8.x

Cause

EL8 introduced the idea of "AppStreams" for EL8 maintainers to use "approved" packages only for future updates. Carbon Black uses its own versions of redis, postgres and python packages which are not in the Appstream

Resolution

1. Disable modules with conflicts
   • Sever 7.4 and below

yum module disable -y redis postgresql python38

• Server 7.5

yum module disable -y redis postgresql python39

2. Clear yum cache

yum clean all

3. Complete installation
