I'am working with ELK in debian9, and i need curator to delete the old index.
so at the first after executing directly
//sudo apt-get update && sudo apt-get install elasticsearch-curator
i was having the older version 4.2.5 but it was not working with my elasticsearch 6.4.1 so I just create sources.list.d/curator.list and add on it deb [arch=amd64] https://packages.elastic.co/curator/5/debian9 stable main
and there i had curator 5.5.4 but [curator --version] or [curator --help] gives me nothing why ?
