How to remove package conflicts due to duplicate RPMs

Introduction

During updates or when using the yum utility, you may run into an error similar to the following:

Error: lvemanager conflicts with lve-wrappers-0.6-11.el7.cloudlinux.x86_64

The following describes how to diagnose this issue as related to duplicate packages and remove the duplicates from your system.

Procedure

CentOS provides a utility to find and remove duplicate packages, as well as clean other package issues.

# package-cleanup --help
Loaded plugins: fastestmirror
Usage:
 package-cleanup: helps find problems in the rpmdb of system and correct them

usage: package-cleanup --problems or --leaves or --orphans or --oldkernels

To determine if your system has duplicate packages installed, use the following command:

# package-cleanup --dupes

If the above command lists any packages, you can then remove the duplicates with the following command:

# package-cleanup --cleandupes

If this command is successful, you have removed the duplicate packages from your system. Please re-attempt the action that resulted in this error initially.
