I found the following commands to update Graylog to 3.2 (from 3.1) but when I do, it breaks my Search. I have Graylog, Elasticsearch and MongoDB on a CentOS box:
$ sudo yum clean all
$ sudo yum install graylog-server
Everything updates like it should but search just says ‘loading…’ at the top. I have tried 3 times and the same thing happens.
