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

will do the trick for you.

The first line tells you what the issue is :x

Hi Mr Generation,
so, after updating the operating system with the command

yum clean all && yum update -y && reboot

If the problem arises, do I execute the two commands that you have indicated to me?

That depends what the error is. If the log entry I quoted appears, yes.

It’s imho a bad idea to just reboot the server after upgrading, because migration might have failed and you’ll never notice it that way. We’d like to encourage you to check the output of the update process to ensure everything was okay.
