came in this morning to find a non working bootable version of elasticsearch.

It should be something like:

sudo bin/elasticsearch-plugin remove ingest-attachment
sudo bin/elasticsearch-plugin install ingest-attachment

sudo /usr/share/elasticsearch/bin/elasticsearch-plugin remove ingest-attachment

So may be manually remove the ingest-attachment dir from the plugins dir?

5

was able to manually remove said package from the plugin dir. after doing so i attempted to reinstall via elasticsearch-plugin

/usr/share/elasticsearch# sudo /usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-attachment
-> Installing ingest-attachment
[ingest-attachment] is no longer a plugin but instead a module packaged with this distribution of Elasticsearch
-> Please restart Elasticsearch to activate any plugins installed
6

So you don't need to install it anymore as it's part of the distribution now.

7

Looks to be correct, but if it's failing.... How does one reinstall it properly?

8

I don't get it. You installed the latest version of Elasticsearch, right?
You just have to start it.

You don't need to reinstall the plugin.

9

Yes, but it seems something is screwed up.

10

Could you share the full logs please?

11

I ended up doing a force reinstall of elastic seems everything is good to go now.
