Plugins are built for a specific version. When you upgrade your ES, you'll have to remove all your plugins and reinstall them with the correct version.
It seems from the last line that you're trying to install 5.6.13 plugin onto a 5.6.12 ES, meaning that the upgrade did not succeed. Can you confirm the new version on the machine? It feels like that message should be the other way around though, that you still have 5.6.12 plugin when trying to run 5.6.13
I stopped ES service, renamed /usr/share/elasticsearch to _old, downloaded ES 5.6.13 RPM from elastic.co and updated through software updater, rebooted, checked http://elastic.server:9200 for version 5.6.13 = succes. Ran all updates fro software updates, rebooted and it worked. Thanks for helping.
