Hi,

I am trying to install shield 2.4.0 plugin in elasticsearch. But I am receiving the following error

root@ip-x-x-x-x:/usr/share/elasticsearch/bin# ./plugin install shield
-> Installing shield...
Trying https://download.elastic.co/elasticsearch/release/org/elasticsearch/plugin/shield/2.4.0/shield-2.4.0.zip ...
ERROR: failed to download out of all possible locations..., use --verbose to get detailed information

I even tried to manually install the plugin but still my getting the following error

root@ip-x-x-x-x:/usr/share/elasticsearch/bin# ./plugin install file:/usr/share/elasticsearch/shield-2.4.0.zip
-> Installing from file:/usr/share/elasticsearch/shield-2.4.0.zip...

It looks like you may have extra jar files in your plugin directory. Can you list the files in that directory?

Hi Jay,

Other than automaton-1.11-8.jar , there is another jar file shield-2.4.0.jar

Hi,

This is the output of ./plugin list

Did you try to just unzip the plugin in that directory or something? I suggest cleaning out the plugins directory and using the installer to install the plugin.
