yum clean all 를 통해 실행해서 모든 메타데이터를 정리해주어야 한다.

# yum clean all

[root@dev-server ~]# yum clean all
Loaded plugins: fastestmirror, langpacks
Cleaning repos: base epel extras mariadb mysql-connectors-community mysql-tools-community mysql57-community updates
Cleaning up list of fastest mirrors
Other repos take up 12 M of disk space (use --verbose for details)

 

다시 yum update 를 해주면 정상적으로 update 되는 것을 확인할 수 있다.
