I am trying to install the following plugins for elasticsearch 2.4.0
with bin/elasticsearch-plugin install [plugin_name]
https://download.elastic.co/elasticsearch/release/org/elasticsearch/plugin/head/2.4.0/head-2.4.0.zip
https://download.elastic.co/elasticsearch/release/org/elasticsearch/plugin/transport-couchbase/2.4.0/transport-couchbase-2.4.0.zip
they are not there, have they been moved?
