Moving ahead, let us see how our Support Engineers fix this error for our customers.

To do so, one possible and common method is via Commandline.

  1. Initially, we log in to the machine using the root account where we face the issue.

    yum clean headers
  3. Clean yum packages cache:
    yum clean packages
  4. Then we clean metadata:
    yum clean metadata
  5. Clean dbcache:
    yum clean dbcache
  6. Clean remaining things:
    yum clean all
  7. Remove clean all RPM database files:
    rm -f /var/lib/rpm/__db.*
  8. Rebuilt RPM Database:
    rpm -vv –rebuilddb
  9. Finally, we run the update command:
    yum update
