I’m unable to get OH 5.2.1 to come up fully. 5.2.0 works fine. 5.2.1 starts up, but never gets javascript or transformations to run. I’ve stopped, cleaned the cache, and restarted, but no luck. If I stop, clean the cache, and reinstall 5.2.0, OH works fine. I have waited hours after the upgrade to see if anything changes, but that hasn’t helped. Below is a log file snippet. The ‘application/javascript’ could not be found messages continue indefinitely.
This is on “Ubuntu 24.04.4 LTS” with:
$ java -version
openjdk version “21.0.12” 2026-07-21 LTS
OpenJDK Runtime Environment Zulu21.52+15-CA (build 21.0.12+8-LTS)
OpenJDK 64-Bit Server VM Zulu21.52+15-CA (build 21.0.12+8-LTS, mixed mode, sharing)
Suggestions?

It’s not just JS based on your logs. The MAP transformation is also unavailable.Restart OH and watch openhab.log for a lint talking about installing add-ons. In particular we care if it complains about no being able to install an add-on.
Often this is a transitory problem related to networking issues and the like. But there could be something else going on here.
I’ve put the full log below. No complaints about not being able to install an add-on. I didn’t let this one run too long, but other attempts are the same - they have the same logs, and transformation and javascript not found errors. It seems like it isn’t even attempting to load the add-on’s or is stuck at a very early stage of the loading?
Are there any debug log settings that would help?
It doesn’t seem like a networking issue, at least on the client side - 5.2.0 loads after a clean cache (multiple times). And I’ve tried 5.2.1 on different days and times with the same issue. Everything else on the linux machine works fine.
