Products

Issue/Introduction

 

    Error seen "could not install puppet" while upgrading OPMS to 10.4.0.2.
    The installation will not complete.

Environment

Release : 10.4

Component : CA App Synthetic Monitor

OS: RHEL

Same puppet-agent package does not appear in CentOS installation

Cause

The required package is

puppet-3.6.2-3.el7.noarch

We are finding that yum will install a more recent  puppet-agent package which is not supported 

Installation logs will contain errors similar to this

"Package puppet-3.6.2-3.el7.noarch is obsoleted by puppet-agent-5.5.12-1.el7sat.x86_64"

Resolution

The puppet-agent package needs to be removed, and the specific puppet package version needs to be installed

Additional Information

The EPEL repository does need to be configured, otherwise there can be further package issues.
Most likely to encounter issues relating to these packages - if EPEL repository is not configured during installation, it can be added and packages reinstalled using these commands

/bin/yum -d 0 -e 0 -y install php-fpm

/bin/yum -d 0 -e 0 -y install docker-ce
