I upgrade Graylog from 4.3 to 5.0 and then to 5.1 but have the same problem at version 5.0 and 5.1. Graylog service not start and nothing is in the graylog server.log file. OS Information: Ubuntu 22.04.3 LTS Package Version: apt list --installed | grep ‘mongod|elasticsearch|graylog|openjdk’:…

So first guess is that you dont have java 17 (as the required version changed from between graylog 4 and 5), or it is somehow not available to graylog Breaking Notes

java -version openjdk version “17.0.8.1” 2023-08-24 OpenJDK Runtime Environment (build 17.0.8.1+1-Ubuntu-0ubuntu122.04) OpenJDK 64-Bit Server VM (build 17.0.8.1+1-Ubuntu-0ubuntu122.04, mixed mode, sharing)

Hi, I looked at it, but in the end I couldn’t find the right graylog-server file to edit. Now I have it, on my system it is located at /etc/default/graylog-server. I re-edited it and graylog now works. Thank you!
