After server reboot, elasticsearch fails to restart. I use only 2 plugins namely ingest-geoip and ingest-user-agent. Same issue is coming when i try to uninstall and install them again. Below is the error log -
```

Also what are the other logs?

At present, there is no plugin installed.
```
[root@gaboli7 gaboli]# cd /usr/share/elasticsearch/
[root@gaboli7 elasticsearch]# bin/elasticsearch-plugin list
[root@gaboli7 elasticsearch]# cd plugins/
[root@gaboli7 plugins]# ls
[root@gaboli7 plugins]#
```
Here is the error that I am getting when I try to install any plugin.
```

Could you ls -a the plugins dir?
May be remove the plugins dir and recreate it?

Please format your code, logs or configuration files using `` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and not the citation button. It will make your post more readable.
Or use markdown style like:
````
```
CODE
```
````
This is the icon to use if you are not using markdown format:
There's a live preview panel for exactly this reasons.
Some thoughts:
- You should not be connected as root but as `elasticsearch` user.
- The [documentation](https://www.elastic.co/guide/en/elasticsearch/plugins/current/installation.html) says to run:
```auto
sudo bin/elasticsearch-plugin install ingest-user-agent
```
May be you did not follow from the start how to properly install elasticsearch? Which package did you install?

Thanks for the tips. I have formatted the code in the previous replies.
It is not only in installing plugins. The problem is there when i try to start elasticsearch.
`service elasticsearch restart`
```

Can you remove the plugins dir, recreate it and start elasticsearch again (without trying to install anything).

Thanks. I just did. Same error is coming - Duplicate key. What are the other options. Do i need to reinstall elasticsearch or downgrade to lower version?

If you can yeah reinstalling by following the installation guide would help.
How did you install it ?

I installed using rpm by following the below link.
[https://www.elastic.co/guide/en/elasticsearch/reference/6.2/rpm.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/rpm.html)
I think the problem is with this auto upgrade manner of elasticsearch. It was working fine before the server reboot. The reboot process has cause the elasticsearch to upgrade to latest version automatically, and hence the issue. How do we turn off auto upgrade?
By the way, I want to keep my existing data in the reistallation process. How to do this?

Ah! Auto upgrades...
> How do we turn off auto upgrade?
I don't know anything about that but IMHO that should be disabled on servers... (If possible)
Was your `elasticsearch.yml` that you shared previously the complete file?
I wonder about:
> Can you remove the plugins dir, recreate it and start elasticsearch again (without trying to install anything).
You said that you did that and that the same error happened.
Just to make sure we are looking in the right direction, could you run:
```auto
sudo rm -r /usr/share/elasticsearch/plugins
sudo mkdir /usr/share/elasticsearch/plugins
sudo chown elasticsearch /usr/share/elasticsearch/plugins
# If using SysV init
sudo -i service elasticsearch start
# If using systemd
sudo systemctl start elasticsearch.service
```
And share the whole commands and their output and the whole elasticsearch logs here, please?
