CENTOS / RHEL: HOW TO FIX DEPENDENCY ISSUE

A dependency occurs when one package depends on another. The RPM database tracks dependency information, so it can, for example, stop attempts to remove packages that other packages depend on or inform users of dependent packages upon installation.

There are four types of dependencies that the RPM system tracks:

  • Requires, which tracks the capabilities a package requires
  • Provides, which tracks the capabilities a package provides for other packages 
  • Conflicts, which describes the capabilities that if installed, conflict with capabilities in a package 
  • Obsoletes, which describes the capabilities that this package will make obsolete 
If there are any missing dependencies, you can install them from the standard repositories using yum install / update.
